If check engine light is on. Get it scanned to find the problem code. They will do this at any auto parts store for free, It may be a bad 02 sensor. Get it scanned. A vehicle can fail a state-mandated smog test because a bad, or faulty, oxygen sensor. remove the O2 sensor from the exhaust pipe ahead of the catalytic converter and look for a change in performance. Good-Day!
No this is not right. If you remove the battery everything resets anyways. If they are talking about relearn procedure, it should only require 50 miles. But if the light is on than either they did something wrong, created another problem, or there was already another one existing. Have the code read and let me know what it is. I'm in Ca too and used to prep european cars for smog, so I do know what I'm looking for. How did the rest do? What were the readings(if possible)?
No the water pump will not affect the smog test. You probably failed the idle? Usually with this age of vehicle you can replace the o2 (oxygen) sensor and it will pass. Cleaning the MAF if it has one cant hurt either if you do it right.
Leak on the intake, bad EGR valve that's not closing. Perhaps a bad O2 sensor, but probably not. The O2 sensor is what detects a rich/lean condition. But when they fail they usually give their own error codes.
Make sure all your tuneup stuff is good, plugs,wires, air filter. If the O2 senser is old it can be Lazy. Make sure the oil is changed before going for test. Make sure its good and warmed up as well. Good luck
Tune it up and replace the 02 sensor that keeps setting the codes bank 2 sensor 1. Have your oil and filter changed right before you go for a retest to. That will clear up 3 codes P0300, 0155 and 0154. You might have to replace the fuel sending unit to get rid of P0463 but if the gauge works OK I'd leave it alone.
