2003 dodge ram 1500 4x4 5.7 hemi 545rfe single cab short box 4.11 gears long tube headers full 3 inch exhaust lowered 4/6 roll pan with hitch and spare tire delete 18s with 30.5 tires and canned tuner. It used to be quick LOL

Does anyone have experience with codes
P0122 throttle position sensor 1 circuit low
P0222 Throttle position sensor 2 curcuit low
also throwing codes
p2115 accelerater pedal position sensor 1 minimum stop performance
p2116 accelerater pedal position sensor 2 minimum stop performance
p2166 accelerater pedal position sensor 1 maximum stop performance
P2167 accelerater pedal position sensor 2 maximum stop performance
p2111 electronic throttle control system unable to close bank 1
p2106 electronic throttle control system forced limited power

this is what originally happened. The red lighting bolt on the dash would pop up and would go into limp mode and it would only do it when it seemed hot under the hood like driving through the city light to light or idling for long periods of time slowly getting worse and worse to the point I'd drive 7 or 8 miles down the highway and soon as if pull in somewhere it would code out.

This is what I've tried. Scanned codes throttle relearn procedures cleared codes got absolutely no throttle response afterwards. Replaced throttle body with known working unit no change. Replaced throttle position sensor (black box under battery) no change. Another relearn procedure and clear codes no change. Disconnected battery over night no change. Probed tps plug and found 2 pins with 4.9 and 5 volts then probed plug at tb and found 2 pins with 4.9 and 5 volts. Tried moving the throttle position back and forth while testing the pins at the tb and nothing.

after all that it has no throttle response but im willing to bet it all stems from codes P0122 and P0222

Previous owner said same lighting bolt happened and it turned out to be the ecu was shot and he had it replaced by the dealership. Thinking I should just get a holley terminator and be done with the factory ecu and wiring

Where do I start? What do i do? Anyone have any tips or pointers would be much appreciated thank you

 

Your APPS (throttle position sensor) is under the fuse box, check the connection there for green crusties. Replace the sensor (ebay) if wiring checks out.

 

I have also seen these codes with two footed drivers. Meaning using your left foot brake and right to push the pedal down on the app sensor. But I would check your connection like previous post. Also check to see if the carpet is rolled under the pedal.

 

Could to much two footet driving cause it to completely stop working like f u stop abusing me? Example no throttle response at all? replaced the apps under the battery box and checked wires for corrosion with no change

 

Have a scanner that can read live data? If not, I do believe you are gonna need one to sort this out properly. You can keep throwing parts at it, until you finally get to the actual problem part, but, that is not a cheap undertaking.

 

I have access to one! Should I start live reading sensors? To be honest I'd be like a cave man with that but i can look up parameters and what i need to know. Or send it to a shop?

 

Make sure you still have your 5v reference circuits, use your multimeter set to 12v dc, don't use a test light. Check pins 2 and 3 to ground. If no power, check pins 2 and 3 for continuity to ground.

Granted, I don't know if those are supplied power KOEO, but I would assume so.

 

If you can get one, yeah, have a look at the live data, see what the PCM is getting for pedal position, and does it change as you step on the pedal.

 

Good idea thanks for the info I'll check soon as I can. If no continuity to ground ill run a jumper wire and try again fingers crossed. Ill do the same for the throttle body just to make sure but i don't know what pins are supposed to be grounded i might ground the tb itself

 

Do not run jumper wires to ground for TCC and O/D. You don't want those solenoids engaged all the time. That would make the truck undriveable.
