Volkswagen Audi Error Code P1196: How to Fix It

Q: How serious is error code P1196?

It's moderate. The check engine light will illuminate, and fuel economy may drop. It can also cause increased emissions. Driving short distances is usually safe, but get it fixed soon.

Q: Can I drive with P1196?

Yes, you can typically drive, but the vehicle may run slightly rich. Avoid long trips until the issue is resolved.

Q: What is Bank 1 Sensor 1?

Bank 1 is the side of the engine with cylinder #1. Sensor 1 is the upstream oxygen sensor, located before the catalytic converter in the exhaust manifold.

Q: Is P1196 common on Audi and VW?

Yes, it's a common fault. The heater element in the oxygen sensor can fail over time due to age or heat cycles.

Q: Do I need to replace both oxygen sensors?

No. Only the faulty sensor (Bank 1 Sensor 1) needs replacement. However, if the other sensor is old, it may be preventative to replace both.

Abstract

Error code P1196 on Volkswagen and Audi vehicles indicates an open circuit in the oxygen sensor heater for Bank 1 Sensor 1 (B1S1). This sensor is located before the catalytic converter and its heater helps the sensor reach operating temperature quickly. An open circuit means the heater element has failed or there's a wiring issue, causing the check engine light to come on and potentially affecting fuel economy and emissions.
