Take it to any Autozone or Advance Auto. They will check it for free! Probably other similar stores will do the same!

These conditions MUST be ruled out entirely.
Check for any of the following conditions/mechanical problems.
AIR INDUCTION SYSTEM - must be free from leaks
ENGINE VACUUM - must be at least 13 inches in neutral
ENGINE VALVE TIMING - must be within specifications
ENGINE COMPRESSION - must be within specifications
ENGINE EXHAUST SYSTEM - must be free of any restrictions or leaks
ENGINE PCV SYSTEM - must flow freely
TORQUE CONVERTER STALL SPEED - must be within specifications
POWER BRAKE BOOSTER - no internal vacuum leaks
FUEL - must be free of contamination
FUEL INJECTOR - plugged or restricted injector; control wire not connected to correct injector.

Unfortunatly, a scan tool will be required to monitor o2 sensor voltages while the engine is running in closed loop. This code you are displaying is NOT an easy solution to trace down. I expect you had an exhaust leak and is why the cats were replaced? Anyway, if so, the PCM can reset the light after a few GOOD trip readings occur that will satisfy the PCM's no fault signal, otherwise the JEEP dealer is going to be your only solution and a pressure test should be performed.

P0301 is #1 cylinder misfire detected and is most likely related to a worn spark plug that is need of replacement. All plugs should be replaced if replacing one. Not sure how many miles you have on this vehicle, or if plugs were ever installed, but this is the basic step to take in diagnosis.

SOURCE: I have a 2007 jeep

"U-codes" (codes beginning with a "U" prefix) are communications faults. Your vehicle is equipped with several computer modules which are all networked to gether on what is called the "Control Area Network" or "CAN". When one of the modules failes to communicate or if there is invalid data being transmitted by one of the modules, a U-code is stored in continuous memory in one or more of the other modules.

In your case, U1403 pertains to invalid or implausible data being recieved from the fuel level sensor by the Powertrain Control Module. Please note that this is NOT a fuel level sensor failure code and does NOT indicate faulty fuel level sensor circuits.

Theory of Operation

The TIPM receives a fuel level signal over CAN B from the Cluster. The TIPM transmits the fuel level message to the PCM over the CAN C bus.

The possible causes of this code are:
> Open or shorted CAN B circuit
> Instrument Cluster (CCN)
> Totally Integrated Power Module (TIPM)
> Powertrain Control Module (PCM)

To properly diagnose tis code, you must use a scan tool to access and verify data on all available modules. You must also determine if this is an active fault or an intermittent fault.

I don't see a fuel level signal problem at the PCM causing your engine to stall. However, the fuel level signal may be getting lost or "scrambled" due to a lack of communications between modules or a malfunctioning module. This could cause all sorts of problems (including stalling).

I would also like to add that my personal experience with this type of problem (communications faults) has taught me that the FIRST thing that should be done is a THOROUGH check of the BATTERY and CHARGING SYSTEM before attempting any communications diagnostics. If your battery is more than 4 years old, it is VERY LIKELY be the ROOT CAUSE of the problem. Computers tend to do all kinds of wierd things when they are not being fed properly.

2014 jeep compass codes po171 and po2173read I changed Oxygen sensor but limp in mode I then changed throtle pedle but limp mode returned how can i fix this ?

code p 0171 refers to system too lean bank 1== causes --intake /exhaust leak---AIR system---MAF/VAF sensor ---fuel pressure/pump--- injectors--- Heated oxygen sensor
by changing the O sensor (oxygen sensor ) you changed the wrong one and so there would be no change to the read out there
code p 2173 refers to throttle actuator control (TAC) system -high air flow detected ===causes --intake system---throttle body
fix the causes and you stand a chance of fixing the problem
