Possible Symptoms:

  • Illuminated check engine light

  • Decreased fuel efficiency

  • Poor acceleration or engine performance

  • Engine misfire or hesitation

Possible Causes:

  • Faulty catalyst temperature sensor

  • Damaged or corroded wiring or connections in the circuit

  • Failed engine control module (ECM)

  • Malfunctioning catalytic converter

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 or corroded wiring or connections in the circuit

  • Replace the engine control module (ECM) if necessary
