So yesterday I put my front o2 in after running without one for a few months and its still throwing 0132. I cleared the codes and it came right back. But the big prob is it came back with 0194. I haven't seen that code for at least a week but it popped up in a parking lot after it stalled out on me. I don't get it.

 

What brand of O2 sensor did you get? It is very possible you got a bad one out of the box. Happened to me when I had the wife's Durango's front sensor changed. Denso (factory brand) or NTK/NGK are best. Bosch and Standard are not known for their quality O2 sensors.

With the P0194, I'd check your fuel pressure on the rails. Could just be another bad sensor, or could be a sign you have a fuel pressure problem.

 

Since we are kinda on topic already here can someone recomend a part number for a replacement fron O2 sensor? my cat is gutted but a Mech told me i should still try to replace the front O2 and do another tune up to get rid of the spudder. Will the lack of back pressure cause any problems? I have a flowmaster 40 behind it. a new cat is is the works soon.

 

No, I drive daily with that same exhaust set up, and have no problems whatsoever. Did you do the non-fouler trick to do away with the rear sensor code?

 

its an ntk. And I'm sorry, its not 0194. Its 1391. I don't know where my brain was this morning

 

So can anyone tell me if the o2 sensor and the crank and cam sensor share the same circuit. I've already changed the crank sensor 3 times and I just pulled the cam sensor and cleaned it and the harness. She's still running like absolute crap

 

P1391 Interm Loss of CMP or CKP

Both the cam, and crank sensors get their power from the PCM, Connector 1, pin 17. O2 sensor does not. Violet wire with white trace. Signal return for crank sensor is C1, pin 8, (Gray/Black) cam sensor is C1, pin 18. (tan/yellow) Check all connectors at both ends, make sure they are clean, and tight. Re-test. If still have the same trouble, replace the cam sensor.

Where did you get your crank sensor? Auto Parts store? Some folks have little to no success with those.

 

I got the first 2 from advanced and the last from napa. if the cam sensor was bad what exactly would it run like.

 

Might wanna grab the sensor from the dealer. Yeah, they are significantly more expensive, but.... they WORK.

Cam sensor controls when injectors fire. If it is reading poorly/wrong, injectors don't fire at the right time..... runs rather funny that way.

 

So I just unplugged the cam sensor and there were no changes. Is it safe to say I need a new one?
