Exhaust Gas Temperature Sensor Circuit Intermittent Bank 2 Sensor 2
Exhaust Gas Temperature sensor circuit malfunction detected. Engine performance and emissions control may be affected.
What You Might Notice
- Check engine light illuminated
- P2087 code stored
- Possible reduced fuel economy
- Potential rough idle
- Emissions system compromised
Most Common Causes
- 1
Loose/Corroded Connectors
Corroded or loose EGT sensor connectors prevent proper signal transmission to the engine computer.
- 2
EGT Sensor Failure
Defective temperature sensor cannot accurately measure exhaust gas temperature.
- 3
Broken Wires/Short to Ground
Damaged wiring or missing insulation creates electrical shorts in the sensor circuit.
- 4
ECU Malfunction
Engine computer failure prevents proper signal reception from the EGT sensor.
How to Diagnose It
- 1
Check Loose/Corroded Connectors — Corroded or loose EGT sensor connectors prevent proper signal transmission to the engine computer.
