P0705

TECHNICAL DESCRIPTION
- When a malfunction of the park/neutral position switch is detected, the transaxle control CPU in the powertrain control module (PCM) outputs a malfunction signal to the engine control CPU in the PCM.

DTC SET CONDITIONS

Check Area, Judgement Criteria
- Park/neutral position switch failure signal is input to the engine control CPU from the transaxle control CPU.

TROUBLESHOOTING HINTS
The most likely causes for this code to be set are:
- Park/neutral position switch failed.
- Open or shorted oil temperature circuit, or loose connector.
- PCM failed.

DIAGNOSIS
Required Special Tool:
MB991502: Scan Tool (MUT-II)

CAUTION: To prevent damage to the scan tool, make sure the ignition switch is off before connecting or disconnecting the scan tool.




STEP 1. Using scan tool MB991502, read the A/T diagnostic trouble code (DTC).
If the A/T-DTC is displayed, refer to Diagnosis. If the A/T- DTC is not displayed, it is suspected that an MFI-DTC has not been erased after repairing the A/T component. If DTC P0705 is displayed again after the MFI-DTC has been erased, replace the PCM.
Then check that the DTC is not output.
