DTC Advanced Diagnostics: P07E4
DTC P07E4 : Unable to Engage Park
General Description
The parking system is operated by driving the parking actuator valve with shift solenoid valves C, D, E, and F. The parking actuator valve stroke sensor which measures the stroke position of the parking actuator valve is structured by two systems as the sensor characteristics are shown as in the figure. When the stroke value of the parking actuator valve stroke sensor is approximately 5.4 mm (0.21 in) or more, the parking system is non-parking position, and when it is approximately -4.1 mm (-0.16 in) or less, it is in parking position. If the parking actuator valve stroke sensor value does not exceed the parking determination value after certain lapsed time since the shift position/mode is selected to P, the transmission control module (TCM) detects a malfunction and stores a DTC.
Monitor Execution, Sequence, Duration, DTC Type
| Execution | Continuous |
| Sequence | None |
| Duration | 4 seconds or more |
| DTC Type | One drive cycle, MIL off, shift position indicator blinks |
Enable Conditions
| Condition | |||
|---|---|---|---|
| Vehicle | ON mode | ||
| Shift position/mode | P |
Malfunction Threshold
The parking actuator valve stroke sensor value is more than -4.1 mm (-0.16 in) after 4 seconds or more since the shift position/mode is selected to P.
Possible Cause
- Valve body assembly failure (parking actuator valve stroke sensor, parking actuator valve, two failure shift solenoid valves out of C, E, and F, shift solenoid valve G, accumulator)
Confirmation Procedure
Operating Condition
- Start the engine, and wait for at least 5 seconds in P position/mode.
- While pressing the brake pedal, shift the transmission to D position/mode, then shift to P position/mode, and wait for at least 5 seconds.
Diagnosis Details
Conditions for setting the DTC
When a malfunction is detected, the shift position indicator blinks and a Pending DTC, a Confirmed DTC, and the freeze data are stored in the TCM memory. The MIL does not come on.
Conditions for clearing the DTC
The shift position indicator comes off by turning the vehicle to the OFF (LOCK) mode. The Pending DTC, the Confirmed DTC, and the freeze data can be cleared with the scan tool clear command.
