Well replacing the throttle position sensor (includes whole throttle pedal assembly) did not fix my problem. I still have the warning light. The codes indicate the throttle position sensor/Idle validation switch. This problem has been intermittent for sometime. Previously I've been able to rectify the problem by shutting down and restarting. This is no longer working. I'm needing to move on out of my present location for work. However I don't want to head out with the warning light on and then have the engine de-rate to idle in the middle of no where. That includes driving it to a distant heavy truck service centre. I've sprayed contact cleaner on the connector at the pedal hoping that would help but no change. Anyone have any ideas on what I else I can try to fix this problem?

Van, Unfortunately mine is the whole throttle pedal assembly with the built in 6 pin sensor. I had a heck of a time finding the right part. REV sent me a link for the correct part but the retailer wanted $600 for it. I found it on Amazon for $150.

Thank you Roland, very much appreciated! That's what I'll do,

Hello, I'm having to replace my throttle pedal assembly with sensor on my 2003 Windsor. I've been having problems such as warning light on and de-rating to idle. The codes were read and determine to be the Throttle Position Sensor. After a lengthy search I was able to determine the GM OEM is made by ACDelco, part# 15150990. Have any of you made this repair? If so, is there a calibration procedure for the new sensor? privcap1

Hi Walter, We have triple slides and our kitchen/cupboards/microwave are on the passenger side. I've looked under the fridge on the other side and no j-box there. There is a junction box on the floor at the back end of the kitchen slide and this box is wired like the one you describe. This j-box has no power to any of the wiring contained with in it. I discovered another j-box (as you describe with the false panel) in the wall behind the shower that is next to the kitchen slide area. There's an access hole for it but it looks like I can only get at it with the kitchen slide in. We've been hit with heavy rain and winds for the past few days so I don't want to bring the slide in yet with it being so wet. I lost power to the front TV double plug too but there's a single "lock-out" outlet right beside the dead one that still has power so using that right now. The dinette circuit has power. Just my "front kitchen" circuit is dead. I've looked high and low for more j-boxes but so far no luck. Next area to check is the basement when the weather improves. Hopefully the problem is that hidden j-box in the wall! Thank you for your direction.

Thank you JDStew, I'm going to keep that close by as it has everything. Unfortunately for me it doesn't have the detailed 110Vac wiring schematic that shows electrical detail such as j-boxes. Dr4, I'm finding that out unfortunately. I have one for 2003 Dynasty and higher models that another member sent me. It is very close my Windsor but not completely. I'm chasing a dead "front kitchen" circuit after my wife's coffee maker caused the circuit to open up somewhere. Unfortunately it didn't pop the breaker. I've gone it down to no continuity from a junction box to the breaker pane (black power wire). However I need to see the wiring path as it relates to the junction boxes.

Hello, I'm a new member. This is definitely an excellent site for Monaco owners! I'm needing the 110vac receptacle wiring diagram for our 2003 Windsor PST. I've been on the downloads section for 2003 models but I'm not seeing the particular diagram I require. Anyone know of a source or area for such a diagram? I'm needing to see wiring paths including junction boxes.
