2002 P5 Trouble Codes

StumpJumpa · Feb 28, 2013

My 2002 P5 is running rough, feels like down one cylinder under 1k rpm, rough idle occasional stalling especially after warmed up and driven for a little while.

Here are the current codes:

P0300 Random Multi Misfire

P0401 Exhaust Gas Recirc

P0117 Coolant Low input

Where should I begin?

Might be your coil packs

Check your coolant temp sensor connector to make sure its connected, and check the wires for cracks/shorts. The voltage coming from the sensor is too low for the ecu. It may be disconnected, broken or have a bad wire. As far as the multiple misfire, its probably caused by your egr being stuck open/closed. Its a very common issue on here. Search around for some info on replacing/cleaning the EGR valve, there should be a couple write ups.
