DTC P0132 - PRIMARY HO2S-1 SENSOR HIGH VOLTAGE Honda Prelude V

  1. Perform PCM reset procedure. See «TESTS W/CODES - INTRODUCTION»(ref-16345) article. Start engine and run at 3000 RPM with no loads and transmission in Park or Neutral until radiator fan comes on. Road test vehicle with transmission in "2" position (A/T) or 4th gear (M/T). Using OBD-II scan tool, check HO2S-1 output voltage during deceleration using fully closed throttle. If voltage stays at one volt or more, go to next step. If voltage does not stay at one volt or more, problem is intermittent. System is okay at this time. Check for poor connections or loose wires between HO2S-1 and PCM connectors.
  2. Turn ignition off. Disconnect HO2S-1, 4-pin connector. Connect a fused jumper wire between HO2S-1, 4-pin harness connector terminals No. 1 (Green/Black wire) and No. 2 (White wire). (Схема №8) Turn ignition on. Using OBD-II scan tool, check HO2S-1 output voltage. If output voltage is one volt or more, go to next step. If output voltage is not one volt or more, replace primary HO2S-1.
  3. Turn ignition off. Using backprobe set, connect a fused jumper wire between PCM 16-pin connector "D" terminal D7 (White wire) and terminal D11 (Green/Black wire). (Схема №4) Turn ignition on. Using OBD-II scan tool, check HO2S-1 output voltage. If voltage is not one volt or more, repair open in suspect wire between PCM 16-pin connector terminal D7 or D11 and HO2S-1 harness connector. (Схема №4)and (Схема №8). See «WIRING DIAGRAMS»(ref-16355) article. If voltage is one volt or more, substitute a known-good PCM and recheck. If symptom or indication goes away, replace original PCM.
