o2 sensors are all bad

o2 sensors are all bad

Postby zackattack [OP] » Jun 29 2012, 2:07am

i went and got my check engine light read, and 6 codes came up front banks 1,2 back banks 1,2 are malfunctioning, there is a heater malfunction (don't remember exactly what it said), and left bank running too lean. i didn't get the codes just what they where. This seems odd that every o2 sensor is bad, but i guess its possible. i talked to some people on the chat and they said it could be something wrong in my engine...hopefully not engines are expensive (but a good reason to go bigger :D ). i ordered two new o2 sensors one pre and one post converter, i plan on changing one side out and seeing if any codes change/ disappear. o and i checked the fuses and they are fine. any help on possible problems in the engine or that would trigger all those codes would be appreciated. thank you.

It sounds like you have more than just an o2 sensor bad. The bank being lean would lead me to believe you have a vacuum leak, or possibly an exhaust leak. Just because a code says something about the o2 sensor does not mean that the sensor is the problem. The one with the bad heater in it will definatly need replaced though.

Thats what I said in the chat. Started working out at the family mechanic and body shop, much more seriously this summer. I have always tinkered out there but im really starting to learn now. Heck its alway been in my blood, :D alway had the urgre to fix things, espically vehicles.
But when he said it was running lean i figured it was something along the lines of a vaccum leak as well

there is antifreeze leaking out of the top somewhere too (puddle on top of engine), its a slow leak. But all the lines seem to be in ok shape no cracking or anything. so if my intake manifold gasket is bad would that cause coolent to leak along with a vacuum leak? or where else should i look?

No coolant goes through the intake manifold itself. You may have a line going to and from the throttle body though.
