CODES

Had codes on a 94gt Manual transmission read and the following was this. 172
HO2S (sensor ) System Lean ( Bank 1 ). What does this mean and what is my
next step to correcting these errors.

2nd step; replace O2 sensor(s). How many miles are on the car ?

Okay... here's a thought. JUST replace the sensor and see what
happens... 99% probability: same thing.

While replacing the sensors at that mileage is probably a good idea, I
have yet to replace one for reading 'lean' and I've taken 4 cars over the
185,000 mark with no perceivable drop in fuel economy and no CEL due to
'lean'

When a sensor gets old, it reacts slower... that's all. And its age is
more to do with the fuel you're giving it and the amount of oil burned.

Well, I've seen sensors that last forever and I've seen sensors that
broke at 60K miles.
