Once the engine is really warmed up and you reset the computer the message does not reappear until the engine is cold again. We have replaced the CVP lines, pugs, leads & rota, catylitic converter and O2 sensors (both). Does anyone have a suggestion please. Chris Jones
I would look at all the fuse .You only need one thats got a fine airline crack .And all eath points in the engine bay .

Check the B+ cable. If you remove the fuse box cover in the engine compartment (on the drivers side), and you'll see a post with a nut on it, securing a group of red wires. The connector should be a clean copper color. If you take it to a shop, have them perform a voltage drop test on the cable. If it is corroded or burnt, replace that cable!

Change the IAC the idle air control. You may be able to clean it and put it back on.

Hi, there are a number of trouble codes associated with the O2 sensors. Some indicate a sensor failure and others indicate a different problem. Can you tell me the trouble code you are getting?

Thanks for choosing FixYa and welcome to the site. OK, bank 1 is located on the same side as the number one cylinder. Most times this is the driver's side. Bank 2 is located on the passenger side of the vehicle, which is opposite of the #1 cylinder. Sensor 1 is before the catylitic converter and sensor 2 is always located after. So for your answer, it is located on the passenger's side before the catylitic converter. That is the location of the bank2 sensor 1 O2 sensor.
