ND engines were used in 2001-2020 for B/C-class passenger cars for Europe, Japan and
emergency markets. Although the series consists of just a single engine, its variants
differ noticeably through the years, make to remember about a whole range of
modifications.

Common Rail fuel system - the fuel is supplied by high pressure pump (or injection
pump) in a common rail and then is injected into the cylinders via the electronically
controlled injectors. The injection pressure - 25/30-160 MPa (mod'01-08) or 30-180 MPa
(mod'15).

High pressure supply pump - Bosch CP3 type.

The history of ND injectors has completed a full cycle: for mod'01 solenoid type ones
were used, for mod'08 they were replaced by piezoelectric type, since mod'15 for most
versions solenoid returned and for mod'17 only solenoid type remained.

Mod'01-02 injectors had a 5-hole nozzle, the individual supply balance was selected by
the group method (when replacing the engine assy, all injectors or engine ECU, the
deterioration parameter had to be reset). Mod'04 injectors received a 6-hole nozzle, an
individual code and DMC (when the injector was first introduced to the ECU, it was
required to write its alphanumeric code). Piezo injectors were available in versions with
a 6/7-hole nozzle. Solenoid injectors mod'15 already had an 8-hole nozzle.

Solenoid type injector. 1 - solenoid, 2 - piston, 3 - nozzle needle. a - injector compensation value, b - DMC

Solenoid injector operation:

- When closed, the valve is held by a spring, and the fuel pressure in the control
chamber holds the piston in the bottom position, which in turn locks the needle in the
closed position (the fuel pressure acting on the bottom of the needle is not enough to
open it).
- When the current supply to the coil, the valve opens the channel, through which fuel
flows to the bottom of the piston. This reduces the pressure in the control chamber and
the pressure increases below the piston, whereby piston moves up. Simultaneously the
needle opens and fuel injection occurs.
- After current cut-off valve is closed by the spring. At this point, the pressure in the
control chamber increases, the piston moves down, the needle closes and injection is
terminated.

Piezoelectric injector operation:

- When voltage is applied to the piezoelectric element its linear dimension changes,
pistons and valve move downward. Overlapped by top of the valve drain channel from
control chamber opens. Pressure in the control chamber drops. The needle moves up
and fuel injection occurs.
- After current cut-off the pistons and valve returns by springs. Drain channel is closed.
The pressure in the control chamber increases. The needle moves down and fuel
injection stops.
- At idling control unit lowers the voltage applied and reduce injector operation speed.
This helps to reduce noise.

Ecology / Exhaust aftertreatment

• An indispensable attribute of all ND versions is EGR (Exhaust Gas Recirculation)

system, which, by bypassing a certain amount of gases at the intake, lowers the
maximum temperature in the cylinder and helps to reduce nitrogen oxide emissions.

Mod'01: Simple system - with a vacuum actuator of EGR valve and without external
cooler.

• DOC (oxidation catalyst) - primary stage of exhaust gas cleaning - oxidizes

hydrocarbons and carbon monoxide to water and carbon dioxide. Used for all versions
since Japanese mod'02.

• DPF (diesel particulate filter) - used to accumulation and combustion of soot particles.
It was installed sequentially with DOC, since mod'08 (optional for Euro-IV and
mandatory for subsequent versions). The condition of the particulate filter is monitored
by a differential pressure sensor.

• NSR catalyst (NOx Storage Reduction), which is supposed to convert NOx, CH and CO
to H2O, CO2 and N2. Appeared on the latest modifications in addition to DPF. Also, an
H2S catalyst appeared at the end, which must fight excess hydrogen sulfide when
cleaning the system from sulfur accumulations.

Experience

The main problem of 1ND-TV engines is total and unavoidable - they have never been
aggregated with automatic transmissions, only with manual or, much less often, with
extremely unsuccessful Toyota MMT robots.

Nevertheless, a number of well-used Yaris and Auris from the European aftermarket
reached the western regions, and in the east, 1-2% of Probox/Succeed run on diesel
fuel.

Looking through the local publications about 1ND-TV motors, at first it is difficult to
understand where so many excellent epithets come from in relation to an objectively
mediocre engine. It's all about the geography of the authors - in Baltic and East
European lands, among the absolute domination of used European cars, even this
Toyota diesel seems reliable and unpretentious.

• Low and/or uneven cylinder compression has become a tradition for rather older
1ND-TV. If, at the same time, there is clearly an excess pressure of crankcase gases
and noticable oil consumption, then the diagnosis and optimal treatment are clear to
everyone. But, unlike gasoline engines, the situation with the offer of good-condition
second hand diesel engines is very sad (since a meager number of such cars was
delivered to the Japanese market).

• Early modifications were susceptible to the mass phenomenon of cylinder head

gasket damage, which often occurred even within the warranty period. The defect
usually developed between the cylinder and the cooling channel, so that oil could be
avoided from ingress in antifreeze, but the rest of the symptoms were classic.

• Like all modern small-displacement diesel engines, 1ND-TV is so efficient that in real
winter conditions it hardly warms up itself and does not provide enough heat to the
saloon.

• Glow plugs are usually remembered when one or two of them remain in order, and
here the main difficulty is to unscrew them from the cylinder head.

• Abundant carbon deposits on the EGR elements and in the intake affect engine
operation and require periodic cleaning. However, practice also shows the ability to

successfully plug EGR (especially early versions).

• Faced with oil consumption and excess oil traces in the intake or exhaust ducts, the
owners sometimes immediately go to replace the turbocharger - however, in some
cases, the cause-and-effect relationships are somewhat different.

• In the fuel system, the main source of problems is the rail pressure regulator, which
is susceptible to both clogging and wear (this seems somewhat unusual comparing to
Denso systems, where pressure is regulated only by metering at the injection pump
inlet). Traditionally, the second place is for injectors - the good thing is that, at least for
mod'01-04, Bosch solenoid injectors are considered both relatively inexpensive and
maintainable. It should be said especially - formally, even solenoid injector cannot be
overhauled, and when they are replaced, it is necessary to program individual injection
volume correction codes in the engine control unit - this engine, apparently, really has
a good durability, because it is able to survive after such garage repair of injectors
without any codes and corrections, that would instantly cause destruction of pistons on
many other diesel engines. Piezo injectors are non-repairable by definition.
And one general pattern: the farther from a large civilization, the more complaints
from owners about a capricious fuel system - that is, even by the turn of the 2020s,
the quality of diesel fuel has not yet reached high world standards everywhere.

• The super-late post-injection mode, which appeared along with the particulate filter,
leads to the fact that part of the fuel flows into the crankcase and significantly
increases the oil level (up to certain limits is considered normal operation - TSB
instructs to clarify this to the owners). Subsequently, the diesel fuel evaporates, but for
the the mechanical part of the engine working on a liquefied oil-fuel mixture is not very
useful, and the oil deteriorating is faster. In the event of regeneration failures or
malfunctioning injectors, the oil level exceeds all permissible limits, requiring
intervention.

Traditionally, it is worth to look at TSB with officially recognized faults and modified
parts:

• EG-4009 "1ND-TV Engine White Smoke from the Exhaust" (01.10.2004)

• EG-7015 "Scraping noise from timing chain" (01.03.2007, timing chain replacement
with sprockets, tensioner slipper and damper for pre-07.2006 cars)

• EG-7046 "1ND Engine jerking" (01.10.2007, ECU replacement)

• EG-0042T-0908 "1ND engine - DTC P0487 exhaust gas recirculation throttle position
control circuit" (11.09.2008, replace the ECU)

• EG-0069T-1208 "1ND Engine - excessive whistling noise from turbocharger during

driving" (12.12.2008).
The problem is the turbine whistling when driving and rpm above 1600 due to
imbalance (because of thermal stress during welding). Prescription - turbocharger
17201-0N030 replacement

• EG-9014 "ND series engine, turbocharger oil leak and white smoke" (01.08.2009)

• EG-9015 "ND series engine, turbocharger noise" (01.08.2009)

• EG-0054T-0110 "Difficult to start followed with unstable idle in cold condition"

(06.01.2010)
The problem is difficult starting of the engine at temperatures below 5°C or unstable
running immediately after a cold start. Prescription - reprogram ECU and replace
injectors (23670-39325> 04009-47133, modified form of the nozzle)

• EG-0071T-0610 "Engine stall, lack of power or MIL-on combined with DTC

• EG-1006 "Change of 1ND-TV engine oil capacity" (22.09.2011, the capacity of

lubrication system has been reduced by about half a liter (apparently, as a reserve for
the fuel draining into the crankcase))

• EG-0047T-0512 "1ND-TV Euro 5 - MIL ON with DTC P2463 on low mileage vehicles"
(09.05.2012, reprogram ECU)

• Pair of TSB related to the oil consumption:

EG-0017T-0411 "1ND-TV Euro 4, Euro 5 - Engine oil consumption REMAN"
(31.01.2017)
EG-0074T-0514 "1ND-TV Euro 4, Euro 5 - Engine oil consumption NON REMAN"
(31.01.2017)
Complaint: the need for frequent oil top-up, blue smoke from exhaust.
Oil consumption of up to 0.3 liters per 1000 km is recognized as the norm, 0.3-0.5 - as
the norm for severe conditions, more than 0.5 - as a warranty case. For some owners
(more lucky) is prescribed to replace the complete cylinder block (short block (11400-
0N060-84, 11400-0N070-84, 11400-0N080). For others is prescribed to just replace a
set of pistons and piston rings, plus check the condition of the block (scratches are
unacceptable with a depth of more than 10 microns (felt with a fingernail) or spots of
complete wear of the hone in the upper part of the liner with an area of more than 1.5
cm2)
