Question1998 dodge caravan 3.3 grand caravan
car started cutting out going down the road
and dying at idle
150,000 miles
ran codes with otc pathfinder and was not able to connect to pcm i was able to read all other controller
no codes on any of them
tried a code reader only and and came up with p0201,202,203,204,205,206,and p0351,352,353
asd relay would not quit clicking
checked all grounds and battery voltage at 12.5
unplugged all connectors on sensors and checked pins
since i had all inputs and outputs i could read i replaced
pcm with remain,
after that the codes when away and i was able to see the computer found a code p1391 asd replaced both the cam and crank sensors, no codes at this time but the asd relay is still clicking and turn the voltage on and off to all the systems it feeds
unplugged all sensors to check for a short
5 volt and 8 volts supply appears good,
have supplied grounds and 12 volts to controller
to check wiring , ign switch seemed to be a problems so i took it apart and checked and cleaned pins it all looked good, the only other thing i notice is when you crank it
after it acts up it acts like a low battery because all the lights dim on the cluster and the starter clicks like it doesn't want to engage, then if you turn the key from the run to start position it will not turn the engine over
has to set a minute and then sometimes it starts right back, anything you could pass on would be helpful
i have read some things on cluster failure on the joints on board but i can not tie this together
thanks
Answerthe ASD relay is controlled by the PCM the power supply is the same for the control and the output. Get a service manual with a good wire diagram so U can see the pin out of the wires look for K51 bark blue/yellow wire and A142 dark green/orange they are the control and output from the ASD to the PCM. U might need to run new wires there could be a short or open on one of them making the relay not hold.
