My '05 Liberty's check engine light came on on Friday. My husband checked for the code and it's P0152. I've looked it up, but not being car savvy, I have no idea what this - 2/1 Sensor Shorted To Voltage / Oxygen sensor input voltage maintained above normal operating range - means. Can someone explain it in layman's terms, please? Thanks!
 
This is showing a problem with the oxygen sensor circuit bank 2 ,which is the passeger side of the engine,sensor 1 should be the sensor before converter towards the front.You need to check the o2 sensor circuit wiring and if everything looks good,then the problem will most likely be the o2 sensor.

Thanks for the replies. Would this have anything to do with the Jeep feeling like the e-brake is on while driving...or is it just a sensor issue? Before I noticed the check engine light flashing, it felt as though I was driving with the e-brake engaged (I wasn't). Once I noticed the light, I stopped, turned off the engine, then turned it back on. The light stayed steady on, no flashing this time. My husband called around to a few mechanics before remembering he could get the code from the Jeep. He was told that it could be that the fuel is not burning off correctly, something to do with the spark plugs or coils.
Again, forgive my ignorance. I don't have the money right now to get a diagnostic check, so thought I'd look this stuff up so we could possibly get a heads up on what might be wrong.
 
O2 sensor

RavynGyrl,
First, welcome to the forum. You can get alot of info from your local auto parts. Usually, places like O'reilly auto or Autozone will give you the code, and a printout of the parts location and how to replace it. Just as an example, my friend had an O2 sensor go out on his Toyota truck. It was located just under the passenger door on the exhaust pipe. I literally took about 5 mins to replace. Total cost was about $100 for the part if I remember correcty. If anything, it was cheaper, but not more than $100. Point is, with a little help, your husband should be able to fix it with just a couple of hand tools and a socket set. I can tell you that this site can help you get it done. good luck.
