2002 Trooper LTD. Power Drive light stuck on.

Postby nick5555 » Fri Sep 10, 2010 1:51 am

2002 Trooper LTD.

The Power Drive Light is stuck on. Pushing and repushing the Power Drive switch has no effect. (ie, the Power Drive lamp remains lit and the transmission continues to operate in Power Drive mode).

Also, since this started occurring, the Check Engine Light will come on and off periodically. For example, the Check Engine Light was on for 5 days until one day it "magically" turned off. And now, this afternoon, the CEL has turned on again.

Any ideas for troubleshooting?

Thank you.

I'd be checking the power drive switch first. Could be shorted. As far as the CEL, have the codes read and post them here. Shouldn't matter if the CEL is on or off, there will still be stored codes.

OK. I'll check the power drive switch. How? Do I need to take off the console? Can I pry off the switch cover? I have a voltmeter but not quite sure how to investigate other than 1) Figure out how to get access to the switch's wires and 2) Look for obvious wire disconnections/discoloration, etc

You can just pull the switch out and unplug it. I think the winter and power button come out together.


Also you need to buy a code reader to see what the CEL is. it could be about 1000 different things.

I had probs with my power/winter mode switches and it was because they were gunked up and sticking. They pop right up out of the console. It will also allow you to disconnect the wires to see if the switch is stuck.

The plastic blade inside the switch was broken. I've been searching parts websites and can't seem to find the switch listed on any of them. Any ideas on how to determine the part number and find a site that sells them?

As for the code reader to determine why the CEL is on intermittently. Any brand or feature recommendations?

Thank you.

Just get one on ebay... (Power/winter switch)
Or grab one at a wrecking yard.

For anyone else looking, the part number and name for the Power/Winter Mode Switch appear to be:
Trans Cont Select or Switch ASM Selector
8-97170-708-2.
Thanks for the ebay tip, William.


Regarding the intermittent CEL. There are 4 codes stored:
P0135: O2 Sensor Heater Circuit Bank 1 Sensor 1
P0141: O2 Sensor Heater Circuit Bank 1 Sensor 2
P0155: O2 Sensor Heater Circuit Bank 2 Sensor 1
P0161: O2 Sensor Heater Circuit Bank 2 Sensor 2

Going to start looking around for more info about the codes now. Any advice greatly appreciated. Thanks.
