Possible Symptoms:

  • Check engine light is illuminated

  • Reduced engine performance

  • Vehicle may fail emissions tests

Possible Causes:

  • Failed catalyst temperature sensor

  • Wiring or connection issues in the circuit

  • Corroded or damaged electrical connections

  • Failed engine control module (ECM)

Related Parts:

  • Catalyst Temperature Sensor: A catalyst is a chemical substance that takes the exhaust gas stream from the engine and converts toxic gases and pollutants to less harmful pollutants. The function of the catalyst temperature sensor is to warn the car computer if temperature of the catalyst goes above the safe limit. Problems lead to harmful emissions out of limit

Possible Solutions:

  • Replace the catalyst temperature sensor

  • Check and repair any damaged wiring or connections

  • Clean any corroded or damaged electrical connections

  • Replace the engine control module (ECM) if necessary
