DTC P1361 Or P1362: TDC Sensor

NOTE: DTC P1361 = TDC Sensor Intermittent Interruption DTC P1362 = TDC Sensor No Signal
  1. Perform PCM reset procedure. See PCM RESET PROCEDURE/CLEARING CODES  under SELF-DIAGNOSTIC SYSTEM. Start engine. If DTC P1361 and/or P1362 resets, go to next step. If DTC P1361 and/or P1362 does not reset, problem is intermittent. System is functioning properly at this time. Check for poor connections or loose wires at TDC sensor 4-pin connector and PCM 31-pin connector. See WIRING DIAGRAMS article. Repair as necessary.
  2. Turn ignition off. Disconnect TDC sensor 4-pin connector. Measure resistance between specified TDC sensor 4-pin connector terminals (sensor side). See TDC SENSOR TERMINAL IDENTIFICATION . If resistance is 1850-2450 ohms, go to next step. If resistance is not as specified, replace TDC sensor.
    TDC SENSOR TERMINAL IDENTIFICATION

    Sensor (DTC) Sensor Terminals No. PCM 31-Pin Connector Terminals No.
    TDC-1 (P1361/P1362) 1 & 2 3 & 13
  3. Check for continuity between ground and individual TDC sensor 4-pin connector terminals No. 1 (Green wire), No. 2 (Red wire), No. 3 (Yellow wire) and No. 4 (Black wire). If continuity does not exist between ground and any terminal, go to next step. If continuity exists between ground and any terminal, replace TDC sensor.
  4. Reconnect TDC sensor 4-pin connector. Disconnect PCM 31-pin connector. Measure resistance between specified PCM 31-pin harness connector terminals. See TDC SENSOR TERMINAL IDENTIFICATION . If resistance is 1850-2450 ohms, go to next step. If resistance is not as specified, repair open in suspect wires between PCM and TDC sensor.
  5. Check for continuity between ground and individual PCM 31-pin harness connector terminals No. 3 (Green wire) and/or No. 4 (Yellow wire). If continuity exists, repair short in suspect wire between PCM 31-pin connector and TDC sensor. If continuity does not exist, substitute a known-good PCM and recheck. If DTCs do not reset, replace original PCM.
