i know there's probably a few threads on the TPS sensor's on a 2001 24H.O. cummins with 6 spd manual. is there multiple sensors? like a pedal sensor? or just the one ontop of the engine? its geting worse as i drive it more and i realy need it fixed. problem is i see these sensors for 80bucks or also 300 and idk what i should buy. so if anyone could help id apreciate it! i scan it and it comes out as TPS/pedal so idk if that means theres also one on the pedal...any help is apreciated

 

What problems are you having? Prob the expensive one. There is a guy that sells an aftermarket one. I forget his name though. I got one and it works fine . Less $$$$ too.

 

What was the code? Need a little more info on the truck any mods,gauges etc.

If it is the APPS (TPS) sensor.. AFTERMARKET APPS THROTTLE POSITION SENSOR ('98.5-'02)-Dodge Cummins Diesel Truck Accessories – Geno’s Garage

What was the problem no power,power sometimes,to much power..

 

what is the code number that is coming up, there should only be one tps mounted to the engine. and u can also test the tps with an ohm meter

 

ill get the code tomarrow mid-day and i have biger turbo, bigger exhuast, aftermarket fuel pump, bullydog outlook program system. and yeah there is only one on the engine but i was wondering if there may be one somewere at the pedal that i didn't know about becuase i seen TPS were the price varied to a hundred bucks in difference... that was my main consern that if there was more then one id replace the wrong one

 

There is only one sensor the APPS (TPS).These do wear out in time,but before you replace it make sure that is the problem.

 

can't you also take a volt reading and adjust them as a first try. I did it on our truck just satisfy me they were correct, didn't really notice a difference. ED

 

well i have done the un-hook batteries and reteach the tps twice it works but after a while it wears off and mess's up again. its doin it more in the cold i think....i scanned and got three codes they are as follows:
1)P0216,injection timing control circuit malfunction
2)P1689, controller area network bus failure (no communication between CM551 and VP44 pump module.
3)P0121, throttle/pedal position sensor/switch A circuit range/ performance
im no expert at this but id say i need a better opinion anyone able to help here????

 

P1689 No Communication Between ECM
and Injection Pump Module Fuel Pump Relay in the PDC is damaged or missing.

Check the relay under the hood drivers side switch it with another one under there.

---AutoMerged DoublePost---

P0216 Fuel Injection Pump Timing Failure -VP44 failure (Physical failure)
- Poor fuel lubricant
-Poor fuel pressure

---AutoMerged DoublePost---

P0121 Accelerator Position Sensor (APPS)
Signal Voltage Too Low APPS sensor failure or out of calibration

 

allright well how to i find the apps? becuase im trying to fix this thing asap...do i need to be lookin at checking and possibly replacing the TPS? or should i be looking for somthing else that led up to the malfunction? my truck has 375000 but idk if this has been replaced before
