OBD-II Generic Error Code P2087: How to Fix It

Q: Can I drive with OBD-II error code P2087?

You can drive short distances, but it may cause increased emissions, poor fuel economy, and reduced engine performance. Long-term driving could damage the catalytic converter or other components. It's best to diagnose and fix the issue promptly.

Q: What does Bank 2 Sensor 2 mean?

Bank 2 refers to the cylinder bank opposite of the one with cylinder #1. Sensor 2 is the downstream sensor after the catalytic converter. On most engines, Bank 2 is the passenger side for inline engines or the rear bank on V-configurations.

Q: How much does it cost to fix OBD-II P2087?

If you DIY, the sensor costs $30-$100. If you hire a mechanic, labor and parts total $150-$400. Additional repairs (wiring, exhaust leaks) can add cost.

Q: Can a bad oxygen sensor cause P2087?

Not directly, but a faulty oxygen sensor can trigger related codes and affect exhaust temperature readings. Always check and repair all associated codes.

Q: Is P2087 the same as P2084?

P2084 is for Bank 1 Sensor 2. They are similar but on different banks. Diagnostics are the same process but on opposite sides of the engine.

Abstract

Error code P2087 indicates an intermittent signal from the exhaust gas temperature sensor on Bank 2, Sensor 2. This sensor monitors the temperature of exhaust gases for emission controls. If the signal is erratic or out of range, the ECU logs this code, which can cause reduced engine performance or increased emissions.
