LOGIC FLOW CHARTS (Monitor Sequence)
DTC SET CONDITIONS

Check Conditions
Solenoid status: either solid ON or OFF.
Shift status: in-gear.
Voltage of battery: 10 volts or more.

Judgement Criteria
Solenoid voltage: 3 volts or less. (0.3 second)
If DTC 33 (P0763) is set consecutively four times, the transmission is locked into 3rd gear as a fail-safe measure, and the "N" range light flashes once per second.
OBD-II DRIVE CYCLE PATTERN
Start the engine, and keep the vehicle stopped in P range for 5 seconds.
TROUBLESHOOTING HINTS (The most likely causes for this code to be set are:
Malfunction of second solenoid valve
Damaged harness, connector
Malfunction of the PCM
