DTC P0133: Primary Heated Oxygen Sensor (Ho2S-1) Slow Response

NOTE: If DTCs P0131, P0132 and/or P0135 are also present, trouble shoot those DTCs before DTC P0133.
  1. Perform PCM reset procedure. See PCM RESET PROCEDURE/CLEARING CODES . Start engine and run at 3000 RPM with no loads and transmission in Park or Neutral until radiator fan comes on. Allow engine to idle. Connect SCS Service Connector (07PAZ-0010100 ). See Figure. Test drive vehicle at 55 MPH, with transmission in "D4" position (A/T) or 5th gear (M/T), until readiness code comes on.
  2. If DTC P0133 resets, replace HO2S-1. If DTC P0133 does not reset, problem is intermittent, system is functioning properly at this time. Check for poor connections or loose wires between HO2S-1 and PCM connectors. Repair as necessary. See the WIRING DIAGRAMS article.
