FAQ Q&A

Q: Is this oxygen sensor for the upstream or downstream position?

A: This is an upstream Air Fuel Ratio (AFR) sensor, typically located before the catalytic converter to manage fuel trimming and engine efficiency.

Q: Will this sensor clear my Check Engine Light (P0031/P1135)?

A: Yes, if your OBD-II codes indicate a heater circuit or signal fault specifically with the Bank 1 Sensor 1 or Bank 2 Sensor 1, this unit 234-9009 is designed to resolve those issues.

Q: Does it come with pre-applied anti-seize lubricant?

A: Most of our high-quality sensors come with a protective cap over pre-applied anti-seize or include a small tube to ensure easy installation and prevent threading issues.
