DTC 31: Problem in CVT Pulley Pressure Control Valve Assembly Circuit

1. Turn the ignition switch OFF.
2. Disconnect the solenoid harness connector (8P).
3. Measure the resistance between solenoid harness connector terminals No. 2 and No. 6.

SOLENOID HARNESS CONNECTOR (8P)

Terminal side of male terminals

Is the resistance 3.8-6.8 ohm;?

YES - Go to step 7.

NO - Go to step 4.

4. Remove the lower valve body assembly.
5. Disconnect the solenoid harness from CVT pulley pressure control valve assembly connector (2P).
6. Measure the resistance between connector terminals at the solenoid connector (2P).

CVT PULLEY PRESSURE CONTROL VALVE ASSEMBLY CONNECTOR (2P)

Terminal side of male terminals

Is the resistance 3.8-6.8 ohm;?

YES - Replace the solenoid harness.

NO - Replace the lower valve body assembly.

7. Disconnect PCM connectors B (24P) and C (22P).

8. Check for continuity between PCM connector terminal B7 and body ground and between C1 and body ground.

PCM CONNECTORS

Wire side of female terminals

YES - Repair short in the wire between PCM connector terminal B7 and solenoid harness connector (8P), or between C1 and solenoid harness connector (8P).

NO - Go to step 9.

9. Reconnect solenoid harness connector (8P).
10. Measure the resistance between PCM connector terminals B7 and C1.

PCM CONNECTORS

Wire side of female terminals

Is the resistance 3.8-6.8 ohm;?

YES - Check for loose terminal fit in the PCM connectors. If necessary, substitute a known-good PCM and recheck.

NO - Repair loose terminals or open in the wires between PCM connector terminals B7 and C1 and the CVT pulley pressure control valve assembly.
