Code No.P07E5: Neutral Condition, P2711: Neutral Condition (D Range)

OPERATION

The ECU detects the current gear/speed according to the output signals from the input and output shaft speed sensor.

DIAGNOSIS CODE SET CONDITIONS

If the neutral gear persists for a predetermined period although the selector lever is moved to the D range, diagnosis codes No. P073E and P2711 are set.

PROBABLE CAUSES

Damaged harness wires and connectors
Malfunction of the A/T-ECU
Malfunction of solenoid valve
Malfunction of the valve body assembly
Malfunction of the transmission assembly
Malfunction of the input shaft speed sensor system (for diagnosis codes P0717, P07BF, P07C0)
Malfunction of the output shaft speed sensor system (for diagnosis codes P0722, P077C, P077D)
Malfunction of the pressure control solenoid SL1 system (for diagnosis codes P0965, P0966, P0967)
Malfunction of the shift solenoid SR system (for diagnosis codes P0973, P0974)
Malfunction of the shift solenoid SB system (for diagnosis codes P0976, P0977)

DIAGNOSIS PROCEDURE

STEP 1. Time lag test

Refer to

Q. Is the check result normal?

	Go to Step 2.

STEP 2. Torque converter stall check

Refer to

Q. Is the check result normal?

	Go to Step 3.

	Go to Step 4.

STEP 3. Hydraulic pressure test

Refer to

Q. Is the check result normal?

	Go to Step 5.

	Go to Step 4.

STEP 4. Solenoid check

Check the pressure control solenoid SL1 and the shift solenoid SR, SB (Refer to

Q. Is the check result normal?

	Replace the transmission assembly.

	Replace the valve body assembly.

STEP 5. Check whether the diagnosis code is set again.

Ignition switch: "LOCK"(OFF) → "ON"
Check again if the diagnosis code is set.

Q. Is diagnosis code No.P07E5, P2711 set?

	Replace the A/T-ECU.

	Intermittent malfunction (Refer to GROUP 00 - How to Cope with Intermittent Malfunction ).
