SYMPTOM
P0753-TRANS 34 SHIFT SOL/TRANS RELAY CIRCUITS

WHEN MONITORED
Continuously with the key ON.

SET CONDITION
This code will set if the voltage detected on the 3-4 Shift Solenoid Control circuit at the PCM is different than the expected voltage.

POSSIBLE CAUSES
- P1765 DTC present
- Intermittent - 3-4 shift solenoid control circuit
- Transmission relay control output
- 3-4 shift solenoid control circuit open
- 3-4 shift solenoid control circuit open internal
- Fused B+ circuit open
- Transmission control relay output circuit open
- 3-4 shift solenoid control circuit short to ground
- 3-4 shift solenoid control circuit short to ground internal
- Transmission relay output circuit short to ground
- 3-4 shift solenoid control circuit short to voltage
- 3-4 shift solenoid control circuit short to solenoid circuits internal
- 3-4 shift solenoid control circuit shorted to other circuits
- 3-4 shift solenoid control circuit short to other circuits internal
- Transmission control relay - poor contacts
- PCM - 3-4 shift solenoid control circuit
