We just replaced the cylinder head because we had low compression in two of the cylinders. We now have codes 108, 118, & 123. We also have code 522 which was present prior to the head exchange.
P0108 (M) MAP Sensor Voltage Too High, P0118 (M) ECT Sensor Voltage Too High Engine coolant temperture sensor input above the
maximum acceptable voltage, P0123 (M) Throttle Positon Sensor Voltage High Throttle position sensor input above the maximum
acceptable voltage range, P0522 Oil Pressure Sensor Low Oil pressure sensor input below acceptable voltage. Sounds like you have an electrical problem, either computer failure or bad sensors. It's hard to believe that you gained so many sensors just from replacing the cylinder head. Disconnect your battery for one minute, then reconnect. Try driving it down the road.

you bypassed the wires that connect to the sensors? that would have been my first guess the harness that plugs into the sensor. after that i would check the ground connection from the ecm. wouldn't hurt to check the battery posts too. if the battery posts are oxidized you can have all kinds of goofy electrical problems. hope that helps.

Aloha We have just replaced all of what you have replaced, plus water pump, fuel pump, pcv valve and 02 sensor. Took it to mechanic today we had misfire on 1,2,6,7. Mechanic said that the 99 dodge is known for bad computers, he checked ours and works great turns out that it was the coil. Ours was jumping 1/4 inch and had a orange/yellow spark. it is supposed to have a 1 inch spark and be blue. This has solved our problems after 527 dollars later.
Check the coil!

TRY REPLACING THE CRANKSHAFT POSITION SENSOR..HAVE SEEN THESE CAUSE MISFIRES AND LOW VOLTAGE DTCS AS PCM THINKS VEHICLE IS NOT RUNNING..ALTERNATOR MAY NOT BE PUTTING OUT PROPERLY

Check the spark plug wiring . There are several places where the wires cross each other. These wire cross points MUST be at right angles to each other. Or you will have a misfiring problem.

It sounds like you're on the right track with the crank sensor.Does the car have injector pulse? A bad crank sensor will also cause no pulse.
