P0366
DTC P0366: CMP (TDC) Sensor B No Signal - M/T Model1. Reset the ECM.
2. Start the engine.
Is DTC P0340, P0341, P0365, or P0366 indicated?
YES - Go to step 3.
NO - Intermittent failure, system is OK at this time. Check for poor connections or loose wires at the CMP (TDC) sensor A/B and at the ECM.
3. Turn the ignition switch OFF.
4. Disconnect the CMP (TDC) sensor A/B 3P connector.
5. Turn the ignition switch ON (II).
6. Measure voltage between CMP (TDC) sensor A/B 3P connector terminal No.3 and body ground.
Is there battery voltage?
YES - Go to step 7.
NO - Repair open in the wire between the ECM and CMP (TDC) sensor A/B.
7. Measure voltage between CMP (TDC) sensor A/B 3P connector terminal No.1 and body ground.
Is there about 5 V?
YES - Go to step 8.
NO - Go to step 10.
8. Measure voltage between CMP (TDC) sensor A/B 3P connector terminals No.2 and No.3.
Is there battery voltage?
YES - Go to step 9.
NO - Repair open in the wire between the CMP (TDC) sensor A/B and G101.
9. Substitute a known-good TDC sensor and recheck.
Is DTC P0340, P0341, P0365, or P0366 indicated?
YES - Substitute a known-good ECM and recheck. If the symptom/indication goes away, replace the original ECM.
NO - Replace the original CMP (TDC) sensor A/B.
10. Measure voltage between ECM connector terminal A11 (A10 *) and body ground.
Is there about 5 V?
YES - Repair open in the wire between the ECM (A11, A10 *) and the CMP (TDC) sensor A/B.
NO - Go to step 11.
11. Turn the ignition switch OFF.
12. Disconnect ECM connector A (31P).
13. Check for continuity between ECM connector terminal A11 (A10 *) and body ground.
Is there continuity?
YES - Repair short in the wire between the ECM (A11, A10 *) and the CMP (TDC) sensor A/B.
NO - Substitute a known-good ECM and recheck. If the symptom/indication goes away, replace the original ECM.
