OBD-II Generic Error Code P2041: How to Fix It

Q: What does code P2041 mean?

P2041 means the exhaust gas temperature sensor for bank 2, sensor 2 is reporting a voltage lower than the expected range. This can be due to a faulty sensor, wiring issues, or a PCM problem.

Q: Can I drive with a P2041 code?

You can drive short distances, but it may cause reduced fuel economy, increased emissions, and potential catalytic converter damage. It's best to diagnose and fix the issue promptly.

Q: Where is bank 2 sensor 2 located?

Bank 2 is the cylinder bank opposite of number 1 cylinder (often passenger side). Sensor 2 is downstream of the catalytic converter, typically on the exhaust pipe after the converter.

Q: How much does it cost to fix P2041?

If you DIY, the part costs $50-$150. Labor at a shop can add $100-$200, totaling $150-$350.

Q: What tools do I need to fix P2041?

You'll need an OBD2 scanner, a multimeter, a wrench set, and safety gloves. Maybe an anti-seize compound for the sensor threads.

Abstract

Error code P2041 indicates that the exhaust gas temperature sensor on bank 2, sensor 2 is reporting a voltage lower than expected. This sensor monitors the temperature of the exhaust gases before the catalytic converter. A low signal can cause reduced engine performance or increased emissions.
