P2087 Code - Exhaust Gas Temperature Sensor Circuit Intermittent Bank 2 Sensor 2
Quick Answer
The Powertrain Control Module (PCM) continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. Common causes include Faulty Exhaust Gas Temperature Sensor (EGTS) Bank 2 Sensor 2, Exhaust Gas Temperature Sensor Bank 2 Sensor 2 harness is open or shorted, Exhaust Gas Temperature Sensor Bank 2 Sensor 2 circuit poor electrical connection. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Frequently Asked Questions about P2087 Code
What does the OBDII code P2087 mean?
P2087 indicates an intermittent issue with the exhaust gas temperature (EGT) sensor circuit on Bank 2, Sensor 2, which monitors exhaust gas temperature downstream of the catalytic converter.
What are the common symptoms of code P2087?
Symptoms may include the check engine light turning on, poor engine performance, increased emissions, and reduced fuel efficiency.
What causes code P2087 to be triggered?
Common causes include a faulty EGT sensor, damaged wiring or connectors, excessive soot buildup on the sensor, or an issue with the sensor's circuitry.
Can driving with code P2087 cause damage?
While driving with this code may not immediately damage the vehicle, prolonged issues could lead to increased emissions, reduced fuel efficiency, and potential damage to the catalytic converter.
How can I diagnose code P2087?
Diagnosis typically involves inspecting the EGT sensor, checking the wiring and connectors for damage or corrosion, and using a multimeter to test the sensor's circuit for continuity.
How is code P2087 fixed?
Repairs may include replacing the faulty EGT sensor, repairing or replacing damaged wiring, cleaning the sensor if it’s clogged with soot, or addressing circuit malfunctions.
Does code P2087 affect emissions?
Yes, a malfunctioning EGT sensor can lead to incorrect exhaust temperature readings, which may cause increased emissions and inefficient combustion.
What is Bank 2, Sensor 2 in code P2087?
Bank 2 refers to the side of the engine opposite Bank 1, typically the side without cylinder 1. Sensor 2 refers to the downstream EGT sensor, located after the catalytic converter.
Can a dirty exhaust system cause code P2087?
Yes, soot or debris buildup can interfere with the EGT sensor’s ability to measure exhaust gas temperatures accurately, potentially triggering this code.
Is code P2087 related to the catalytic converter?
Indirectly, yes. The downstream EGT sensor monitors exhaust temperatures after the catalytic converter, and issues with the sensor can affect the converter's efficiency.
