DTC P0760 SHIFT CONTROL SOLENOID VALVE C CIRCUIT MALFUNCTION 

COMPONENT LOCATION

GENERAL DESCRIPTION 

The Automatic transmission changes the gear position of the transmission by utilizing a combination of clutches 
and brakes, which are controlled by solenoid valves. This automatic transmission consists of a: LR (Low and 
Reverse Brake), 2ND (2nd Brake), UD (Under Drive Clutch), OD (Over Drive Clutch), REV (Reverse Clutch), 
and a RED (Reduction Brake, only for 5 speed transmissions). 

The 2ND Brake is engaged in the 2nd gear and 4th gear positions. 

DTC DESCRIPTION 

The TCM checks the Under Drive Clutch Control Signal by monitoring the feedback signal from the solenoid 
valve drive circuit. If an unexpected signal is monitored, (For example, high voltage is detected when low 
voltage is expected or low voltage is detected when high voltage is expected) the TCM judges that 2nd Brake 
drive control solenoid circuit is malfunctioning and sets this code.



Fault is intermittent caused by poor contact in the sensor's and/or TCM (PCM)'s connector or was 
repaired and TCM (PCM) memory was not cleared. Thoroughly check connectors for looseness, 
poor connection, bending, corrosion, contamination, deterioration or damage. Repair or replace as 
necessary and go to "VERIFICATION OF VEHICLE REPAIR" procedure.  

NO  



Go to "TERMINAL & CONNECTOR INSPECTION" procedure.  

TERMINAL & CONNECTOR INSPECTION 

Refer to DTC P0750. 

POWER SUPPLY CIRCUIT INSPECTION 

Refer to DTC P0755. 

SIGNAL CIRCUIT INSPECTION 

1. Check signal circuit open inspection 

1. Ignition "OFF".  

2. Disconnect "A/T SOLENOID VALVE" connector and "PCM" connector.  

3. Measure resistance between terminal "4" of the ATM SOLENOID VALVE harness connector and 

terminal "45" of the PCM/TCM harness connector. 

Specification: approx. 0 ohms
