  1. Perform PCM reset procedure. See SELF-DIAGNOSTICS - INTRODUCTION 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 scan tool, check HO2S-1 output voltage during deceleration using fully closed throttle. If voltage stays at 1.5 volts or more, go to next step. If voltage does not stay at 1.5 volts or more, problem is intermittent. System is okay at this time. Check for poor connections or loose wires at HO2S-1 and PCM connectors.
  2. Turn ignition off. Disconnect HO2S-1, 4-pin connector. Connect a fused jumper wire between HO2S-1 harness connector terminals No. 1 (White wire) and No. 2 (Green/Black wire). (Схема №7) Turn ignition on. Using scan tool, check HO2S-1 output voltage. If output voltage is 1.5 volts or more, go to next step. If output voltage is not 1.5 volts or more, replace HO2S-1.
  3. Turn ignition off. Using backprobe set, connect a fused jumper wire between PCM 31-pin connector "C" terminal No. 16 (White wire) and terminal No. 18 (Green/Black wire). Turn ignition on. Using scan tool, check HO2S-1 output voltage. If output voltage is 1.5 volts or more, repair open in White wire between PCM 31-pin connector "C" and HO2S-1. See appropriate wiring diagram in WIRING DIAGRAMS article. If output voltage is not 1.5 volts or more, substitute a known-good PCM and recheck. See SUBSTITUTING PCM in SELF-DIAGNOSTICS - INTRODUCTION article. If symptom or indication goes away, replace original PCM.
