DTC P0335: - CKP Sensor No Signal DTC P0336: - CKP Sensor Intermittent Interruption Reset the ECM/PCM (see page 11-4). Start the engine. Is DTC P0335 and/or P0336 indicated? YES - Go to step 3. NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the CKP sensor and at the ECM/PCM. Turn the ignition switch OFF. Disconnect the CKP sensor 3P connector. Turn the ignition switch ON (II). Measure voltage between the CKP sensor 3P connector terminal No. 3 and body ground. CKP SENSOR 3P CONNECTOR Wire side of female terminals Is there battery voltage? YES - Go to step 7. NO - Repair open in the wire between the PGM-FI main relay 1 and the CKP sensor.

Measure voltage between the CKP sensor 3P connector terminal No. 1 and body ground. CKP SENSOR 3P CONNECTOR Wire side of female terminals Is there about 5 V? YES - Go to step 8. NO - Go to step 10. Measure voltage between the CKP sensor 3P connector terminals No. 2 and No. 3. CKP SENSOR 3P CONNECTOR Wire side of female terminals Is there battery voltage? YES - Go to step 9. NO - Repair open in the wire between the CKP sensor and G101. Substitute a known-good CKP sensor and recheck. Is DTC P0335 and/or P0336 indicated? YES - Substitute a known-good ECM/PCM and recheck (see page 11-6). If symptom/indication goes away, replace the original ECM/PCM. NO - Replace the original CKP sensor.
