Change TP Sensor on 04 focus, 2.0DOC, and still get code PO122?


Possible but I doubt it.
The code means the computer is not getting a signal back from the sensor.
To test the sensor you would have checked for the reference voltage on the yellow wire, then check the resistance of the sensor with a meter.
You probably don't have voltage going to the sensor, or else the harness is bad between the sensor and the computer.
The return voltage is low at idle and goes up as the throttle is opened. ( I think )

2002 Jeep Wrangler. Engine warning light is on. After turning the key switch on/off 3 times the following two codes appear. P0123 and P0300.


Hi, I'm not sure these are related. The first is your throttle position sensor. This tells the engine how hard you are pushing on the accelerator. The second code is random misfire., which I've never seen caused by the TPS. That said, I would fix the TPS first. Check the wiring and connector for any issues. If the wiring looks good, I would replace it and calibrate the new sensor. If this doesn't clear up the code 300, please read my post on misfires for additional troubleshooting steps: http://www.fixya.com/cars/r6715318-causes_gasoline_engine_misfires . These are generic instructions.

Trouble Code: P0123

TP Sensor Circuit High Input
Possible Causes:


TP Sensor sweep TP Sensor ground circuit is open TP Sensor signal circuit is open or is shorted to VREF (5v) TP Sensor is damaged or has failed (an internal open circuit) Possible intermittent condition PCM has failed


Trouble Code: P0300

Multiple Cylinder Misfire Detected
Possible Causes:


Air leak in the intake manifold, or in the EGR or EVAP system Base engine mechanical fault that affects two or more cylinders Erratic or interrupted CKP or CMP Sensor signals Fuel delivery component fault that affects two or more cylinders (i.e., a contaminated, dirty or sticking fuel injector) Ignition system problem (coil or plug) in two or more cylinders Vehicle driven with low fuel pressure or while very low on fuel
