DTC P0132: Front Oxygen Sensor (O2S) Circuit Range/Performance Problem (High Input) - 2.2L & Legacy 2.5L M/T

  1. Turn ignition off. Connect scan tool. Turn ignition on. If DTC P1130, P1131, P1132, P1133 and/or P1134 exist, diagnose and repair those DTCs. If DTC P0132 is only DTC set, go to next step.
  2. Start and ensure engine operating temperature is more than 160°F (70°C). If engine is already warmed up, operate engine at idle for one minute. Observe front O2S output signal value. If voltage value is .85-1.15 volt during idle, go to next step. If value is not .85-1.15 volt, go to step  4.
  3. Slowly accelerate engine (five seconds) from idle to 5,000 RPM a total of 5 times. Using scan tool, select LED operation mode. If rear O2S LED blinks, check for poor contact at front and rear O2S connectors. If LED does not blink, check rear O2S circuit. See appropriate wiring diagram in WIRING DIAGRAMS article.
  4. Check exhaust system for damage or loose components. Repair or replace exhaust system components as necessary. If exhaust system is okay, replace front O2S.
