2000 Dodge Ram 1500 Van. 146,800 miles. Recent tune-up, coil pack too. Replaced trans and computer less than a year ago. New battery just a few months ago. It's been idling rough, so I know I need to check the idle control module. Today it just shut off on the freeway. I was able to drop into neutral and restart. I've been getting intermittent "no bus" fault. BUT - holy mother of all engine codes - today after stumbling around, the van threw seven (7) codes! 0403, 0753, 1282, 1687, 1491, 1303, and 1202. Where do I start, besides a bad ground? Is there a common denominator here?

 

P0453 is an egr code.... I didn't think your van even HAD egr....

P0753 Trans 3-4 Shift Sol/Trans Relay Circs
P1282 Accelerator Pedal Pos Sens2 Low Voltage <- There is only one sensor I am aware of, this code shouldn't even apply.
P1687 No Cluster BUS Message
P1491 Radiator Fan Ctrl Relay Circ <- do you even HAVE an electric fan??
P1303 <- I can't find anything on this...... not for dodge.
P1202 <-same here. Nothing found.

That's just odd...... Think I would reset the PCM, (disconnect battery, turn on headlights, wait five minutes, turn off headlights, reconnect battery.) Take it for a drive, and see what happens.

 

I reset the PCM as instructed - I'll keep you posted as to how things go. It did throw one more code earlier today before I reset the PCM - 0443.

 

That's a purge valve control circuit code. Probably bad valve......

 

Hmmm.... and that may fix at least some of the issues I am experiencing. Not an expensive fix, and the valve is 18 years old. I'll take a look at that.

 

Well, I took it to a shop - almost had to have it towed. After a week, they tell me it needs a PCM. I replaced the PCM and the Transmission less than a year ago. I'm being told the replaced PCM only had a 90 day warranty (not sure I believe that) - and they want to sell me another for $ 800 to $ 900. I've looked around online, see them for much less. Anyone have a recommendation for a good place to get a remanufactured PCM?
