CEL P0152-O2 SENSOR 2/1 CIRCUIT VOLTAGE TOO HIGH

[portlandsrt]

Just had a CEL pop up last night....
I did a search for this specific code and it looks like no one here has had one before... Can anyone lend me some insight on what this is?????

thats usally the sign of a bad o2, its kinda like a spike that the computer throws to the sensor to see if there working. or if your catless and have 02 sims one of the sims can be bad. this could also make the motor run rich

Thanks for your response... I am Catless... So I'm betting that one of my sims is bad. Is there any way for me to tell which one is bad???

the code : CEL P0152-O2 SENSOR 2/1 CIRCUIT VOLTAGE TOO HIGH

sensor 2/1, i think is passenger side front sensor...... the front sensors have to do with your air/fuel feedback, the back two are for cat sensing.....
you can get the sensor thru the dealer for ~ $40.00, it's easy to swap out.

Just ordered the sensor.. It was $70 from the dealer...

wow, gone up since the last time i qouted them $33 up to $62..... you could order online to $46.00 (6th one down):

UPDATE: When I fired up my truck this morning,,, NO CEL... Drove my usual 15 miles to work,,, NO CEL..
Can anyone give me an explanation on why this specific CEL just went away? I understand why other CEL's go away,,, they go through a certain amount of cycles and if everythings good,,, the light turns off..
But something like a O2 sensor,, what would make it be "good again"...?

 

[portlandsrt]

Any ideas???

Any ideas???

The P.C.M. monitors o2 activity,when it sees everyone is on line,It cancels the code and moves it from an active to a stored code!!!!
Kudos on your repair!!:rock:

Yeah, but I didn't repair anything... I hadn't installed the new O2 sensor yet. The CEL just went away.

It really could simply be an intermittent issue. Once it goes away, it clears.
