While waiting for the new sensors to arrive I went and got that second opinion. You were right, only one is testing bad. Sensor 1, bank 1. Also getting a error code P1443 EVAPORATIVE EMMISION SYSTEM CONTOL VALVE. I would think these these are somehow related problems. Any chance these things are covered under that fabulous warrantee they advertize? The car has 65K, bought in Aug. 04
I have just joined the forum and as techfella said, this is great info.
I have a 2004 Epica with 61000 km and the check engine light just came on. Would it be a safe bet to change the oxygen sensors without getting a computer reading or are there a bunch of other things that can be wrong? Also, I would be interested in hearing back from techfella as to the progress and difficulty of changing the sensors. I am fairly good with car repairs once I know what is wrong.
I would like to add that since I bought this car in Sept 04, it has been one repair after another and now that the bumper to bumber is over, I don't want to pay too much for repairs.
Max is right about getting the code scan. After I had mine done, I found one other thing that with need fixing beyond the O2 sensors. The sensors haven't arrived yet so I can't give you any update on the progress. When I do jump on it I will let you know. I like my Verona, but from everything I've read the car has a bad rep on the reliability side. Parts are not that easy to find (aftermarket expecially) and the repair cost is about average. My plan is to get it back to a reasonable trade in value and sell it. Good luck.
You probably laid out some heavy $'s on all the sensors Tech. You COULD not take receipt of the soon to be delivered sensors you're waiting on (sending them back), or if possible, simply return the ones you don't need. Don't know what your suppliers return policy is. Just a thought.
Not sure of your location, but RockAuto out of NJ ships same day.
And Frenz...you can pick up a OBD2 scanner off e-bay for $30.00 plus shipping as I did IF you think that you could use it on future scanning needs as well.
Rock Auto is where I ordered from, paid in the $60-70 range. It did cross my mind to replace only the bank 1 sensor found on the scan and send the others back. I just figured if one is bad the others might not be far behind. Is that not good logic?
Good thing I scanned my car. Nothing to do with the oxygen sensors. I got code P0700 (Transmission module) P0442 (small leak) and P1673 (hot engine light). GM changed my fuel guage sensor about a month ago. Is it possible that they caused the P0442 error? My gas cap seems to be fine. From what I have read, the other 2 codes are not anything to be concerned about.
I don't know what to say about your code issues. I wouldn't neglect any trouble code the computer spits out. Seems like the domino effect happens if you let one go, something else pops up. Example, I went to the dealer today just to confirm what Autozone found regarding the oxygen sensor. Now I'm getting two other errors, P1443 evaporator emmission value and one for the wheel speed sensor. What ever that is, the part cost $200+ they say it's a computerized sensor.
Anyway, I just got the O2 sensors today and will let you know how the installation go's.
