Except D16Y5 M/T

WARNING: This page is about a different car, the 2000 Honda Civic. However, it is still accessible from the selected car via links, so may be relevant.
  1. Perform PCM reset procedure. See PCM RESET PROCEDURE/CLEARING DTCS in SELF-DIAGNOSTICS - INTRODUCTION article. Start engine. If DTC P1336 and/or P1337 is indicated, go to next step. If DTC P1336 and P1337 are not indicated, problem is intermittent. System is okay at this time. Check for poor connections or loose wires at CKF sensor and PCM connectors. See appropriate wiring diagram in WIRING DIAGRAMS article. Also check for loose CKF sensor mounting bolt. Repair as necessary.
  2. Turn ignition off. Disconnect CKF sensor Gray connector. Measure resistance between CKF sensor Gray connector terminals No. 1 (White wire) and No. 3 (Blue wire). If resistance is 1600-3200 ohms, go to next step. If resistance is not 1600-3200 ohms, replace CKF sensor.
  3. Check for continuity between ground and CKF sensor Gray connector terminal No. 1 (White wire) and terminal No. 3 (Blue wire), individually. If continuity does not exist, go to next step. If continuity exists, replace CKF sensor.
  4. Turn ignition off. Reconnect CKF sensor Gray connector. Disconnect PCM 31-pin connector "C". See Figure. Measure resistance between PCM 31-pin harness connector "C" terminals No. 22 (Blue/Red wire) and No. 31 (White/Red wire). If resistance is 1600-3200 ohms, go to next step. If resistance is not 1600-3200 ohms, check for open in suspect wire between CKF sensor and PCM 31-pin connector "C". See appropriate wiring diagram in WIRING DIAGRAMS article.
  5. Check for continuity between ground and PCM 31-pin harness connector "C" terminal No. 22 (Blue/Red wire). If continuity exists, check for short in Blue/Red wire between PCM 31-pin connector "C" and CKF sensor. If continuity does not exist, substitute a known-good PCM and recheck. If symptom or problem goes away, replace original PCM.
