P0336
DTC P0336: CKP Sensor Intermittent Interruption1. Reset the ECM with the HDS.
2. Start the engine.
3. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0335 and/or P0336 indicated?
YES - Go to step 4.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose terminals at the CKP sensor and at the ECM.
4. Turn the ignition switch OFF.
5. Disconnect the CKP sensor 3P connector.
6. Turn the ignition switch ON (II).
7. Measure voltage between CKP sensor 3P connector terminal No. 3 and body ground.
Is there battery voltage?
YES - Go to step 8.
NO - Repair open in the wire between PGM-FI main relay 1 and the CKP sensor.
8. Measure voltage between CKP sensor 3P connector terminal No. 1 and body ground.
Is there about 5 V?
YES - Go to step 9.
NO - Go to step 12.
9. Measure voltage between CKP sensor 3P connector terminals No. 2 and No. 3.
Is there battery voltage?
YES - Go to step 10.
NO - Repair open in the BRN/YEL wire between the CKP sensor and G101.
10. Substitute a known-good CKP sensor and recheck.
11. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0335 and/or P0336 indicated?
YES - Update the ECM if it does not have the latest software, or substitute a known-good ECM, then recheck. If the symptom/indication goes away with a known-good ECM, replace the original ECM.
NO - Replace the original CKP sensor.
12. Measure voltage between ECM connector terminal A7 and body ground.
Is there about 5 V?
YES - Repair open in the wire between the ECM (A7) and the CKP sensor.
NO - Go to step 13.
13. Turn the ignition switch OFF.
14. Wait for 1 minute. If the radiator fan is running, wait for 1 minute after the radiator fan stops.
15. Disconnect ECM connector A (31P).
16. Check for continuity between ECM connector terminal A7 and body ground.
Is there continuity?
YES - Repair short in the wire between the ECM (A7) and the CKP sensor.
NO - Update the ECM if it does not have the latest software, or substitute a known-good ECM, then recheck. If the symptom/indication goes away with a known-good ECM, replace the original ECM.
