I have a 2003, dodge ram 1500, 4X4, 5.7 Hemi engine. I have to codes P0340, P0344, & P0132, the AC blows but don't cool the truck, the cruse control keeps going off when i'm driving down the road. Last yr I change the spark plugs, replaced the starter, replaced the camshaft sensor. I recently replaced the spark plug wires, the O2 sensors, the crankshaft sensor & replace the battery. I have also stuck refegerent in it. can someone please help me. I am sick & tired of dealing with this. I about to take into the shop.

 

This section is for PC problems, not car problems. I will move the thread for you.

 

P0132 indicates that the signal wire is shorted to voltage. Unplug the sensor and using a voltmeter check voltage on the signal wire harness side. If the voltage is present with the senosr unplugged and key on engine off, then the wire is shorted to voltage somewhere. If it leaves when unplugging the connector, then the sensor is at fault or the installation. Be sure to replace with a factory 02 sensor as the other replacements never seem to work. Both other codes are camshaft pos sensor related. Check the actual wires themselves and trace them as far as you can. Usually replacing it will clear these codes. Have you had your codes cleared after replacing this stuff?

 

yes i have ceared all of the codes after replacing these parts. It also sounds misses sometimes when it idling & sometimes it takes a while to start also. I'm thinking that i need a new PCM, but i really don't want to buy one.

 

Cruise control kicking off could simply be a bad ABS wheel sensor. Mine use to do that. You have to change the wheel bearing hub assembly though. I bought mine off ebay for about $65 shipped. I dont *think* you can buy just the sensor.

I think this may be what you are talking about.

 

could also be the vacume pump on the cruise going bad or a vacume leak

 

Everywhere i look on here the only thing people are having Cruise Control problems are through,1: Speed Sensor, 2: Vacum Leak
