Chrysler Voyager 3.3 1998 - Runs rough and stalls, multiple codes #
Posted by Ken Hudson on June 19, 2011, 2:55 pm
Year of Manufacture *: 1998 Engine Size and Code *: 3.3 litre ( Optional ) Scanner Used: DRB III
Hi
Normally this vehicle runs well, but on an intermittent basis will run rough and stall with engine check light illuminated and security light flashing. Once it stalls, clicking noises coming from EGR valve and ASD relay, plus fuel pump relay. Also DRB III drops out with “no comms” message and then re-establishes connection. Checked pin 16 and 4/5 on 16 way diagnostic plug, ground seems to go high for a second or so (nothing conclusive). Also engine check light becomes fluttery as if a power failure / ground fault occurs Following codes are logged but will clear, but once engine starts to run rough and stall, the same codes return. The vehicle will all of a sudden return to running well for no apparent reason. P1685 invalid skim message P0351 ignition coil No1 primary circuit P0352 ignition coil No2 primary circuit P0353 ignition coil No3 primary circuit P0202 Injector No2 control circuit P0203 Injector No3 control circuit P0204 Injector No4 control circuit P0205 Injector No5 control circuit Carried out wiggle test on all looms and fuse boxes, cleaned engine earths. Checked ignition circuit to ecu (NBV) but not carried out amp draw Checked ECU grounds and carried out volt drop test to battery ground Drove the vehicle the other day for 20 miles without a glitch, now its even difficult to start
They say when approaching diagnostics, it is similar to landing an aircraft You have to approach the runway at the right angle before you get anywhere With this vehicle I seem to have lost the airfield. Help needed - any advice welcome Ken Hudson Ps Customer does not want to spend any serious money !!!!!

Hi Ken, I would have thought that you either have to look for the lowest common denominator (the common link between all components)or analyise/record one circuit in detail whilst the vehicle is playing up. HTH

Hi Ken, In my experience these things are bl**dy awful for wires chafing around PCM and FCM. I had a complete non-runner with a high resistance supply to the PCM. Found a corroded wire beside/below the nearside headlamp. Had another with intermittent headlamps and other problems which turned out to be a chafed databus wire which was shorting to earth. My suggestion would be to have a good look around this area. You will almost certainly need to remove air intake, battery tray and possibly headlamp for a proper look. HTH Shaun.

update- removed battery and tray etc. checked loom for corrosion etc - none found - opened loom up in various places and found no evidence of poor insulation / chafing etc and more to the point, wiggle tests through out have no bearing on fault. monitored ecm output ground to automatic shutdown relay and this is going high very quickly(flickers relay). My view is that the ecm is losing its internal ground, or there is an input sensor shorting the ecm to create a ecu re-set.I think the customer is now going to take a view on how we move forward as the car we have loaned her is highlighting the huge petrol bill she gets each week from driving the 3.3 litre Voyager guzzler.

Hi Ken,
if you think its a ECU earth fault why not scope the output to the relay and all the ECU earths at the same time? HTH
