Nissan Fault Codes
11 Crankshaft Angle Sensor, Circuit from 1988 to 1990 and Crankshaft Position Sensor from 91
at 96
12 Air Flow Meter/Open or Closed Circuit
13 Cylinder Temperature Sensor (Maxima and 300ZX); for others it is Sensor Circuit
Temperature
14 The Vehicle Speed Sensor circuit is open
The mixture ratio is too lean despite the feedback control; injector
covered
21 Ignition signal in the primary circuit not read by the ECU during startup or adjustment
22 Fuel pump circuit (Maximo and 300ZX from '87 onwards); the others are
idle control circuit or valve
23 Idle switch (throttle valve switch) open circuit signal
24 Malfunction of the neutral/Park switch
The circuit of the minimum speed control valve is open or closed.
26 Turbo Load
28 Cooling Fan
29 Rich fuel system
31 Electronic Injection Models from 84 to 86; Problems in the Air Conditioning system;
other models: Internal ECU problem
32 Electronic injection models from 84 to 86; check the engine. Other models: EGR failure.
(California models)
33 Sensor or circuit (300ZX left side) of oxygen - other models: EGR failure
34 Knock Sensor (Knock or Rattle)
35 Exhaust gas temperature sensor (California models)
36 EGR Transducer
37 Closed circuit control/front oxygen sensor (Maxima)
41 Maxima and 300ZX from 84 to 87; fuel temperature sensor circuit. Other models:
air temperature sensor circuit
42 300ZX from 88 onwards; fuel temperature sensor circuit. Other models:
throttle position sensor circuit
The mix ratio is very poor despite feedback control; clogging of
injector (Sentra 87). Other models: the throttle sensor circuit is closed or open
44 There are no error codes stored in the ECU
45 Escape in injector (California models only)
51 Open injector circuit (California models only)
53 Oxygen sensor (300ZX right side)
54 Short circuit between the Automatic Transmission Control (TCU) and the ECU
It indicates a normal operation of the system
63 ignition failure detected - cylinder no. 6
64 ignition failure detected - cylinder no. 5
65 ignition failure detected - cylinder no. 4
66 ignition failure detected - cylinder no. 3
67 ignition failure detected - cylinder no. 2
68 ignition failure detected - cylinder no. 1
71 ignition failure detected - random
72 Catalytic converter failure (right side)
74 EVAP pressure sensor
75 Escape in the EVAP
76 Fuel injection system
77 Rear oxygen sensor
81 Bypass valve and vacuum cutoff
82 Crankshaft sensor
84 Communication between the fuel injection system and automatic transmission
85 VTC Solenoid
87 EVAP canister purge control
91 Front oxygen sensor
95 Crankshaft sensor
98 Coolant temperature sensor
101 Camshaft sensor
103 Park/Neutral Switch
105 Canister and EGR control valve
108 Control of the EVAP volume
