My 03 Jeep TPS may be bad. Is it covered under my 7/70 Warranty ?

The emmisions light comes on from time to time. And my cruise control shut down while going down the highway. The code points to the TPS. Just wondering if this should be covered in my 7/70 warranty ?? Thanks.

7/70 is basicly for powertrain. It could be covered under the emmisions warranty. Call the dealer.

My 2006 f150 has new brakes and rotors,fluid full but my dash brake light stays on. Soon as you start it and the whole time you drive. Also the cruise quit too. Once the light went off then the cruise


This sounds like the brake light switch or the control switch on the brake pedal is bad or loose. Check under the dash above the brake pedal there should be one or two switches that tell the brake lights to come on and the cruise control to shut down.

2005 Subaru Outback. Trip odometer suddenly said Err 55, cruise control started flashing, ABS lit up, and check engine light had come on. I noticed a day later that the regular odometer had frozen,


I found this under Fixya; 2006 Subaru Outback; there were 25 answers: The problem is not with an emission issue as you would expect with a check engine light. The ER 55 code on the odometer means that there is a loss of communication with the ECU, that is why the check engine light is on and cruise light flashing. for what ever reason whenever your check engine light comes on the cruise becomes disabled. Lame I know. I work in the service department and have seen this issue a lot. The only real way to fix this issue is to go the dealer and have them do a reflash for your vehicle. If the ECU is bad it is covered under the federal emmission wrty for 8 years or 80,000 miles

Jeep Grand Cherokee P1490


okay you have a few problems here, lets start with the rear taillight problem, these jeeps are none for the sockets going bad, this would be simple to test with atest light,

next po1489 and 1490 have nothing to do with plugs or fuel filter, these codes are for the high and low speed fan control. the cooling fan on radiator. so i would first start with the testing of the cooling fan, if the engine is running hot due to fans not working then this would cause loss of power and may damage engine, this may be due to bad relays or fan, the code po 0122 is for the tps, this may be a bad tps or a wiring problem, there are to ways to do this one is to test and the other is to replace, if you have a tester and a meter you can test voltage ground and ref signal to tps or you can replace it and if the problem is still there (the code) then you will have to test.
the tps code may be the problem for lack of power.
as far as the cruise control, the cruise will not operate with a check engine light on, this is the future, computer will shut it down. the light problems, coming on at times will need some testing and is hard for me to help you with out more info,

good day

The cruise on my 2006 jeep gr. Cherokee started acting up. It was set and then it started accelerating for no reason. I reset it and was fine. It did the same thing later that day but now it cant be set....


The problem is with the PCM (Powertrain Control Module). It made be malfunctioning or may just need to be reset (disconnecting and reconnecting the battery). If it ends up being a bad PCM then bring it to the dealership and the PCM is covered under warranty for 8 years 80,000 miles.

Hope this helps.

Cruise control on 98 chevy venture stops working


The Venture uses an electronic Cruise Control and doesnt require vacume. I would suspect the cruise module under the hood, or the lever on the steering colum to be bad.

2006 jeep grand cherokee - cruise light does not come on, and cruise does not engage. after cruise started not working, the cruise light came on briefly one more time.


Most likely a problem with the PCM (Powertrain Control Module). It may be malfunction or it may just need to be reset. Try disconnecting and reconnecting the battery for about a minute. If that doesn't work then go to the dealer and they will run a diagnostic test for about $95. If the PCM is the problem it will be covered under manufacture warranty for 8 years 80,000 miles.

Hope this helps.

2003 jeep grand cherokee cruise control not working.


Ok, the '03 Jeep Grand Cherokee uses a small vacuum line to control the servos. Since your light comes on, it's obviously getting power. 9 out of 10 times it's the vacuum hose.
Pop the hood and look on the passenger side towards the back for the engine coolant reservoir. It's most likely underneath it so you may have to remove the res. Check the vacuum hose and all vac. connections then check the electrical connections. If that's not the problem, check the cruise control connection to the throttle linkage.
If that still doesn't do it, you may need use scan tools and diagnostic procedures that are out of the scope of home mechanics.
Wish ya luck!

Cruise control quit working in 1995 Jeep Grand Cherokee. fuses all seem to be fine. also is having trouble shifting gears. it is an automatic, straight V6, with 172,000 miles.


there are a few things that can inhibit the cruise control on a jeep, and the more prevalent one is a vacuum leak in that circuit (hose) that runs off the intake manifold (rearmost one with the check valve in it), which then jogs over to the passenger side of the vehicle, and takes a dive down under the battery tray to the vacuum reservoir. if you are creative about making a plug after pulling the hose off the intake manifold, and then disconnect the tiny hose from the cruise control actuator, also on the passenger side of the engine compartment, and then pull vacuum either with your mouth or a small vacuum pump, then you've proven that this is not the reason the system is not working. Also, if your valve cover rearmost vacuum line to the intake manifold is 'leaky', it will cause this as well as other issues, such as defroster or air conditioning not to blow thru the air vents into the crew cabin, but only onto the windshield defroster vents. if this turns out not to be the problem, and the hose and valve cover fitting are in good shape (the center section of this is plastic and brittle and subject to cracking and breaking, by the way!), it's a good time to start to suspect the brake pedal switch. this switch has contacts that do more than just allow the brake lights to come on, there are cruise control 'inhibit' contacts in this switch as well. and yes, these do tend to go bad. in any case, if the instrument cluster blue light never comes on, it suggests that the system has more than vacuum problems and this brake pedal switch is most likely the cause if there is no other known electrical problem, such as an open circuit for the cruise control. I wish I could offer more, but the liklihood of the actuator being the root cause of this failure, is pretty slim, and there is not much else for you to play with, though there is probably an Engine Control Module possibility here, as a group of five or six Cruise Control wires actually go into that box. In any case, do the vacuum hose and vacuum checks first, then start to think about the 30 dollar switch on the brake pedal.

Electronic throttle control, cruise control


You need to have the codes read. The electronic throttle relies on an APP sensor and a TPS sensor. A problem with either one of these will cause this. Also, the cruise would be affected by this, as there is no cruise servo, it's controlled be the electronic throttle body.
