Code 32 Or 42: Air Inlet Damper Position Sensor/Servomotor Circuit

1999 Toyota Camry XLE, 2.2 GSECTION Code 32 Or 42: Air Inlet Damper Position Sensor/Servomotor Circuit
NOTE: For Code 42, see CODE 42: AIR INLET SERVOMOTOR CIRCUIT  for additional trouble shooting procedures.
  1. Remove A/C control assembly, leaving harness connectors connected. See A/C CONTROL ASSEMBLY  under REMOVAL & INSTALLATION. Turn ignition on. Backprobe between terminals A17-7 (Blue/Yellow wire) and A16-1 (White/Red wire) at A/C control assembly harness connector. See Figure.
  2. Measure sensor voltage while alternately pressing fresh air and recirculated air buttons to activate air inlet damper. See AIR INLET DAMPER POSITION CIRCUIT VOLTAGE SPECIFICATIONS  table.
  3. If voltage is not as specified, test air inlet servomotor. See AIR INLET SERVOMOTOR  under TESTING. Replace servomotor if it is defective. If servomotor is okay, go to next step.
  4. Inspect wiring harness and connectors between sensor and A/C control assembly. Repair as necessary. If wiring harness and connectors are okay, temporarily substitute known-good A/C control assembly. Retest system.
