My car first came on with a check engine light at 53,000 miles. Got it coded that the car prompted and it was reading P015B which indicates bank 1 sensor 1 of O2 sensors experiencing a lean to rich response issue.

The next day my car started to run rough and the oil light came on as well with an error message reporting low oil pressure. I recently got an oil change done a week prior. I did take the car back to where I got the oil change. The company did not find any issues with the oil change but proceeded to change it anyway again.

P015B: questions drivers ask

What does code P015B mean?

P015B is a manufacturer-specific powertrain code (engine, transmission, fuel and emissions), so its exact definition depends on the carmaker and is not in the generic OBD-II list. 4 owners reported it to NHTSA, most often for the Chevrolet Cruze (2), Chevrolet Suburban (1), Ford Ecosport (1); their reports describe what happened.

Which cars get code P015B most often?

In NHTSA owner complaints, P015B is mentioned most for the Chevrolet Cruze (2), Chevrolet Suburban (1), Ford Ecosport (1), across 3 models and model years 2012 to 2018. Popular models collect more reports because more of them are on the road.

Is there a recall for code P015B?

No NHTSA recall text names P015B directly. 2 recalls on the cars that report this code concern the same component owners name most (Engine); they may or may not relate to the code. Check your VIN at nhtsa.gov/recalls.

What should I do if my car shows P015B?

Write down when the code appeared and what the car did (warning lights, loss of power, noises, speed, weather). Check your VIN for open recalls at nhtsa.gov/recalls, ask a dealer or independent workshop to read the stored freeze-frame data before anyone clears the code, and keep the repair order. If the car loses power in traffic, stop driving it. CarHooq does not diagnose: these are owner reports and official recall notices, not repair advice.
