The fault code P2091 indicates a problem with the downstream oxygen sensor in the exhaust system. The estimated repair time for this issue is 1.0 hour. The cost of fixing this issue can vary depending on the auto repair shop, but it is common for them to charge between $75 and $150 per hour.

Other factors that may influence the cost include the location of the repair shop, the type of vehicle, and the severity of the issue.

The fault code P2091 is related to the engine’s fuel system. When this code appears, the engine light or service engine soon warning light will turn on. This is an indication that there is a problem with the fuel system that needs to be addressed.

One of the symptoms of this fault code is a long engine.

This means that the engine takes longer than usual to start or may take longer to reach its normal operating temperature.

This can be caused by a variety of issues, such as a clogged fuel filter or a malfunctioning fuel pump. It is important to address this fault code as soon as possible to prevent further damage to the engine. Ignoring this code can lead to decreased fuel efficiency, reduced engine performance, and even engine damage.

A qualified mechanic should be consulted to diagnose and fix the issue causing the P2091 fault code.

What are the possible causes of the P2091 fault code?

If you’re experiencing the P2091 fault code, it could be due to a faulty Exhaust Camshaft Position Actuator Solenoid in Bank 1, an open or shorted harness, a poor electrical connection in the solenoid circuit, or a faulty Engine Control Module (ECM). To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for any damaged components or broken, bent, pushed out, or corroded connector pins.
