DTC Troubleshooting: P1895 (39-1)
| DTC P1895: | Problem in CVT Pulley Pressure Control Valve Circuit |
NOTE: Record all freeze data before you troubleshoot.
| 1. | Disconnect CVT pulley pressure control valve connector. |
| 2. | Measure the resistance between connector terminals at the control valve connector.
 CVT PULLEY PRESSURE CONTROLVALVE CONNECTORTerminal side of male terminals Is the resistance 3.8-6.8 W? YES - Go to 3. NO - Faulty the CVT pulley pressure control valve, replace the control valve body.n |
| 3. | Disconnect the battery negative terminal. |
| 4. | Disconnect PCM connectors B (24P) and C (22P). |
| 5. | Check for continuity between PCM connector terminal B7 and body ground, and between terminal C1 and body ground.
 DNLS+ (GRN/WHT)B (24P)C (22P)DNLS- (PNK/BLK)PCM CONNECTORSWire side of female terminalsAre there continuity? YES - Repair short to ground in the wire between PCM connector terminal B7 and the CVT pulley pressure control valve connector, and between terminal C1 and the CVT pulley pressure control valve connector.n NO - Go to 6. |
| 6. | Reconnect CVT pulley pressure control valve connector. |
| 7. | Measure the resistance between PCM connector terminals B7 and C1.
 DNLS+ (GRN/WHT)B (24P)C (22P)DNLS- (PNK/BLK)PCM CONNECTORSWire side of female terminalsIs the resistance 3.8-6.8 W? YES - Update the PCM if it does not have the latest software, or subsutitute a known-good PCM, then recheck. If the symptom/ indication goes away with a known-good PCM, replace the original PCM.n NO - Repair loose terminal or open in the wires between PCM connector terminals B7 and C1, and the CVT pulley pressure control valve connector.n |
