Welcome to the forum from Texas. Please go to the new members section and tell us about yourself and your Cruiser.


Have you gone to the internet and google/bing the codes? What I saw was TPS and low voltage.

should not have a 122 and a 123 unless you unplugged the TPS while running. suggest you clear the codes and report which come back. otherwise you'll be getting all kinds of odd advice on here

Originally i was getting low voltage codes...now i think its down to the tps car breaks up around 3k rpm...with live data running it says tps is doing nothing when i hit the gas....i took tps off tried rotating a little before then bolting it on then scanner read 99.6% use....why wont the tps catch the flap....its like it isnt sitting in the right spot so it will get a readding when the throttle body butterfly starts rotating does that mean its shot?

I would suggest checking the wire harness from the camshaft sensor to the PCM. It is very common problem that the wire harness drops down on the half shaft or chassis and start shorting out wires on the 2001 & 2002 Pt Cruisers. It might be affecting the battery voltage.

Steve, that's the CAMSHAFT wiring harness that drops down and hits the halfshaft. Did it to mine.

easier since you have a scanner... When you take the sensor off the throttle body, connect the wires to it, turn the key to the run position (without starting).. does the sensor value read correctly as you rotate the middle part?

99.6 is obviously wrong. if it reads 0-20% at idle. that would be normal the car tares whatever percent to 0 like a digital scale
