P2196 Ford -

Question

I have 2 fault codes, P2196 & P2198, truck running really rich, code descriptions are lack of heated oxygen sensor, bank 1 sensor1 and bank 2 sensor 1. Which oxygen sensors could be faulty?

Answer 1

Hi there,

Bank 1 and bank 2 front O2 sensors could be the problem, but since the issue is affecting both sides of the engine it's not likely an O2 sensor problem. Here is a list of other possible causes.
