Are you traveling high ground like Rocky Mountain?

I will remove the ground cable for 4 minutes to reset all data in ECU.///clock and radio stations too : (

Let the ECU to relearn the local environment parameter.



Here's so info on how to prevent vapor lock

Ride with full tank of gas but NO TOP OFF.

Crack open gas cap carefully during rest stops to release / equalize gas tank pressure'

thats correct, may have bad ecm (computer) or bad wire to crank sensor from ecm, also ive run into this problem and it was the new sensor i put in was no good and aftermarket,also cam sensor can do this, and also make sure the 5 volt feed wire is good,good luck hope this helps.

Testimonial: "It ended up being the cam sensor. Thanks for the info. Fixed it right up."

SOURCE: Jeep is giving a code of p0340 which is telling me

go to autozones website they have free diagrams

SOURCE: are the 3.7 liter jeep liberty known for head

any vehicle can have any component fail at anytime. The only way to know is to have it inspected for the correct diagnosis if your experiencing problems. If you want a second opinion because you don't trust the first one then your only going to get that at a repair shop.

I'm assuming that you are talkin about P0122 Code - Throttle Position Sensor/Switch A Circuit Low Input

A P0122 code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too low a voltage. On some vehicles that lower limit is 0.17 - 0.20 volts (V).

Did you adjust it when you installed it? If the signal value is less than .17V then the PCM sets this code. Could be an open or a short to ground in the signal circuit. Or you may have lost the 5Volt reference voltage.

Symptoms may include:
* Rough or low idle
* Stalling
* Surging
* No/little acceleration
* other symptoms may also be present

Causes: A code P0122 may mean that one or more of the following has happened:
* TPS not mounted securely
* TPS circuit short to ground or another wire
* Faulty TPS
* Damaged computer (PCM)

Possible Solutions: Some recommended troubleshooting and repair steps are:
* Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
* Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
* If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
* If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.

Hope helps (remember comment and rate this).
