P2086 GMC Code - Exhaust Gas Temperature Sensor Circuit Range/Performance 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 P2086 GMC Code
What does the OBDII code P2086 mean for my GMC vehicle?
The P2086 code indicates that there is a range or performance issue with the exhaust gas temperature (EGT) sensor circuit for Bank 2 Sensor 2, which monitors the temperature of the exhaust gases.
What are common symptoms of the P2086 code?
Common symptoms include the check engine light being illuminated, decreased engine performance, increased fuel consumption, and potential issues with emissions controls.
What could cause the P2086 code to trigger?
Causes can include a faulty exhaust gas temperature sensor, damaged wiring or connectors in the sensor circuit, exhaust leaks, or issues with the engine's computer (ECM).
How can I diagnose the P2086 code?
Start by using an OBDII scanner to confirm the code and check for any related codes. Inspect the wiring and connectors of the EGT sensor for damage, and test the sensor's resistance and voltage according to the manufacturer's specifications.
Can I drive my vehicle with a P2086 code?
While it is possible to drive with a P2086 code, it is not recommended as it may lead to reduced engine performance and increased emissions, potentially causing further damage over time.
What repairs are commonly needed for a P2086 code?
Common repairs include replacing the faulty exhaust gas temperature sensor, repairing or replacing damaged wiring or connectors, or addressing any exhaust leaks that may be affecting the sensor's readings.
How much does it typically cost to fix a P2086 code?
Repair costs can vary widely depending on the specific issue, but replacing the EGT sensor usually costs between $100 to $300, including parts and labor.
Is the P2086 code serious?
Yes, the P2086 code can indicate issues that may affect engine performance and emissions. Addressing it promptly helps ensure your vehicle runs efficiently and meets environmental standards.
Can the P2086 code be reset, and will it come back?
The code can be reset using an OBDII scanner, but if the underlying issue is not resolved, the code is likely to return after some driving cycles.
