P0535

2017-10-10

Description:

  • The fault code P0535 indicates that there is an issue with the A/C evaporator temperature sensor circuit. This sensor is responsible for monitoring the temperature of the A/C evaporator and sending the information to the engine control module (ECM). A fault in this circuit can cause the A/C system to malfunction, resulting in poor cooling performance.

Possible Symptoms:

  • Poor cooling performance from the A/C system

  • Illuminated A/C warning light

  • A/C system may not function at all

  • Engine may run poorly or stall, especially during idle or low speeds.

Possible Causes:

  • Failed A/C evaporator temperature sensor

  • Faulty wiring or connections in the circuit

  • Loose or corroded electrical connections

  • Failed engine control module (ECM)

Related Parts:

  • A/C Evaporator Temperature Sensor: Prevents the air conditioning refrigerant from becoming too cold. Problems lead to reduced AC cooling

Possible Solutions:

  • Replace the A/C evaporator temperature sensor

  • Check and repair any damaged wiring or connections

  • Tighten or clean any loose or corroded electrical connections

  • Replace the engine control module (ECM) if necessary
