DTC P0894

Forward clutch power transmission malfunction

DETECTION CONDITION

•  With the engine running and the selector lever in the D or M range, all of the following conditions are met:

―  ATF temperature 20 °C {68 °F} or more

―  Vehicle speed 0 km/h {0 mph} (brake on)

―  Even when 3 s or more has passed since the engine has started, the turbine speed will not decrease to less than 187.5 rpm.

Diagnostic support note:

•  This is a continuous monitor (CCM).

•  The MIL does not illuminate if the PCM detects above malfunction conditions during the first drive cycle.

•  A PENDING CODE is not available.

•  FREEZE FRAME DATA is not available.

•  The AT warning light illuminates.

•  DTCs are stored in the PCM memory.

POSSIBLE CAUSE

•  Forward clutch not engaged or slipped

•  Short to power supply in wiring harness between shift solenoid A terminal B and PCM terminal 1D (ZY)/1AZ (Z6)/1B (LF)

•  Shift solenoid A stuck on

•  VSS malfunction

•  PCM malfunction

Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY DTCS • Turn the ignition switch to the LOCK position, then to the ON position. • Verify the DTCs in the PCM memory. • Are DTCs P0720, P0752, and P0753 output?	Yes	Go to the applicable DTC inspection.
2		No	Replace the forward clutch, then go to the next step.
3	VERIFY TROUBLESHOOTING OF DTC P0894 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC from the memory using the M-MDS. • Warm up the engine. • With the selector lever in the D range and the vehicle stopped (brake on), wait 3 s or more. • Are any DTCs present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION[ZJ, ZY, Z6].) (See PCM REMOVAL/INSTALLATION[LF, L3].)
3		No	No concern is detected. Go to the next step.
4	VERIFY AFTER REPAIR PROCEDURE • Perform the “After Repair Procedure”. (See AFTER REPAIR PROCEDURE[FN4A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE[FN4A-EL].)
4		No	DTC troubleshooting completed.
