The TPS sensor MAY be bad. I would check that first. Throttle Position Sensor.

2004 intrepid replaced MAP sensor and cleared codes. about 100 miles later drove to work, 8hrs later started it and engine started intermittently revving at idle and in gear. had to keep heavy on throttle...


TPS wears in spots and can cause intermittent problems like you described. Try turning off the car and unpluging the TPS. Start the car and see if smooths out the idle/reving problem while the TPS is unplugged. If yes replace the TPS.

Hoe to fix Chrysler 300M: 99 30m Chrysler have the codes po700,po734,po733,po122,po113,po108


codes PO700, PO733, PO734 are all transmission codes all have to do with inproper outputshaft speed could be a bad outut shaft sensor but most likely the transmission is slipping, and that is not good if the transmission is shipping you will need to replace it, but try chaning the fluid and filter and and see if that does not take care of the problem.

code PO122 is the TPS sensor, code PO108 is the MAP sensor the MAP sensor can set the TPS code but the TPS can not set the MAP code so i would start with the MAP sensor ..... code PO113 is the intake air temp. sensor check the wiring on the top of the engine to make suer there is not a bad spot in the harness if all looks good then replace the sensor, but the way all 3 sensors use a commoin ground circuit so check the wiring before you replace any of the sensors......good luck

Looks to be a pedal position sensor.
You may need to see your dealer parts service to get an idea on what may cause this code.

Code p0122 and p0123 after changing computer


Hi.

The problem is regarding TPS (throttle position sensor located in throttle body). Both codes are TPS voltage out of range (low and high) If you get both codes at once, then :

TPS may be defective,
wiring to TPS may be shorted to ground.
There may be a problem in the +5V circuit powering the TPS.
There may be a problem with ECU connector.

'97 Lumina code PO122


You might want to check the wiring to the sensor for cracks, breaks, or melted spots. On the other hand, it is possible for a sensor to be faulty from the start, but unlikely. I think it is a wiring problem, remeber the fault code P0122 means a fault in the TPS circuit, not just the TPS itself, get IT??
