So this past summer I all of a sudden started experiencing the reduced engine power, service engine light and traction control light all came on. I did a little digging and discovered water on the floor of the truck. So I did a little research and found that others had similar issues with their sunroof drains clogging and water backing up into the truck and getting the main big black connector behind the drivers kick panel wet. I pulled off the kick panel and sure enough the connector was wet. I let the truck dry out for a couple of days and lubed up the connectors with some dielectric grease and the truck was good until about 3 weeks ago. I was driving home from work after a snowstorm here and about halfway home my security light came on. I was nervous about the car turning off on me so I pulled over and restarted the car and the security light went away. I then continued home and about a mile from home my reduced engine power, service engine and traction light came on and I couldn't get the car about 2k rpms. I managed to make it home even though I could barely get up the driveway.
I immediately thought maybe my sunroof had leaked again with all the snow sitting on top of it, so I pulled the kick panel off and checked the connector and it looked dry, and so did the floor around it so I was at a loss. I did however find a little bit of corrison in the plug so I unplugged the battery and did some cleaning on the connector along with some contact cleaner and it looked good. When I went to hook the battery back up I noticed some corrison around the battery, I then also then noticed that it appeared to be the original battery and figured it would need to be replaced soon anyway so I did that knowing that a bad battery could make the car do weird electrical issues. Well I thought I was smooth sailing and the truck was good for about 5 days then all of a sudden I'm back to square one and can't drive the truck again as it has the reduced engine light and the CEL as well. I stopped by the dealership and they mentioned that its probably the throttle position sensor or the accelerator pedal position sensor. I then went to autozone and got the codes checked: they are p0120, p0700, p1125, p2120, p2138, c0276 and c0241. Being the Accelerator pedal position sensor didn't appear that hard to change and was about a $50 part I decided I'd start with that. Well I put the new APP sensor in and still no go.
Can anyone please help, I'm a single mom and can't afford to take it to the dealership!
