SOURCE: code p0122 and p0123 after changing computer


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.

SOURCE: what could be wrong when you get code p0122 and

throttle position sensor. check the electrical connection to the sensor for corrosion and security.

If the van is running well, you can try and reset the MIL and see if the codes come back.

If there are symptoms such as the engine is stumbling or hesitating, carefully inspect all wiring and connectors that lead to the TPS. More than likely the problem is with the TPS wiring. Check the voltage at the TPS (refer to a service manual for your vehicle for this specific information). If the voltage spikes or is too high (over 4.65 volts with key on, engine off), then that is indicative of a problem. Carefully trace each wire from the TPS wiring harness to check for breaks, rubbing against other components, etc.

Multiple codes on 2002 dodge durango

This many codes sounds like a wiring issue. You need to inspect all the wiring. If you have rabbits in your area, they eat wires. If not then it is likely to be a corroded or loose ground. You need to get a wiring diagram etc.

I have a 2004 jeep wrangler and i am reading the codes p0122 p0123 and p0432 can anyone let me know what these dtc's mean and if possible how to fix what it broken

P0122 - Throttle Position (TP) Sensor Circuit Low Voltage
P0123 - Throttle Position (TP) Sensor Circuit High Voltage
without checking it 1st I would guess the TPS is most likely defective.
P0432 - Catalyst System Low Efficiency Bank 2, you may have to replace the Catalytic convertor, it may be worn out,
A WORD OF CAUTION: Don't use aftermarket cats, they tend to reset the same code due to compatibility issues, also replace the cat monitor sensor (looks like an O2 sensor) located just to the rear of the bank 2 cat converter.
