Introduction
Some vehicles equipped with 1MZFE (V6) engines without VVTi may exhibit a rough idle and/or a M.I.L. ON condition with a diagnostic trouble code or codes for misfire caused by an improperly operating ignition coil assembly. Production changes have been implemented to prevent this condition from occuring. S 2001 model year Japan built Camry vehicles equipped with 1MZFE engines (V6). S 19982001 model year North American built Camry vehicles equipped with 1MZFE engines (V6) S 1998 1999 model year Avalon vehicles. S 1998 2000 model year Sienna vehicles. S 1999 2002 model year Solara vehicles equipped with 1MZFE engines produced BEFORE the Production Change Effective VIN shown below.

Repair Procedure
1. Confirm if vehicle is currently misfiring, running rough or hesitating. If YES Go to Step 2. If NO Review Freeze Frame Data and attempt to operate vehicle under similar driving conditions see notes below for information that makes it more likely to duplicate misfire.
NOTE: The following activities will turn off misfire detection: S Changing engine RPM greater than 150 RPM. S Changing throttle position quickly. Misfire duplication can be duplicated most readily when the engine speed and throttle angle are held nearly constant for at least 2 minutes.
NOTE: When misfire monitor is active, ignition value will change on Data List. When pending misfire DTC is set, MISFIRE RPM and MISFIRE LOAD will show values.

Is the cylinder(s) identified by the DTC(s) misfiring? If YES Go to Step 3. If NO Follow normal diagnostics for applicable DTC in Technical Information System (TIS) in applicable Repair Manual: Diagnostics: SFI: P030#. 3. Swap suspect ignition coil(s) from cylinder that is misfiring to cylinder that is not misfiring. 4. Using Diagnostic Tester, confirm that misfire is now occurring in cylinder that has suspect ignition coil(s). Has misfire followed swapped ignition coil(s)? If YES Replace ignition coil(s) and go to Step 5. If NO Follow normal diagnostics in Technical Information System (TIS) for applicable Repair Manual: Diagnostics: SFI: P030#. 5. Confirm misfire has been eliminated (0% at all times) using Diagnostic Tester while engine is idling.
NOTE: If misfire percent is any value other than 0% at any time, then that cylinder is misfiring.
