Engine light came on. dealer states the TPS is bad. how much does it cost

Did you watch the TPS numbers on a scan tool in your car?
TPS code means TPS bad or wiring or TPS adjustment.
Change the TPS as they cost nothing and do wear out.

dealer scanned? with there fancy tool>? if not you may fail.
the transmission needs full scans not autozoned,
did you ask the dealer if there are transmission TSB updates
new update transmission programs? y/n.?

so how do you know that switch is bad, ?
no engine stated, not even gas or diesel. 42RLE trans?
no symptoms stated.
just asking (vague parts) ok



there are 4 factors here. and more.

1. whats really bad. (parts) (did you prove it bad and test it yet?)
2. cost of parts.
3. labor costs (vary all over earth , no country or town stated)
4. and other related damage, collision or rust.

my guess, wild, right p/n switch contact failure.
number 3 below out and new in?

my guess, 1hr labor ($100)
and $40 part

part ID 3 here , that?

http://www.factorychryslerparts.com/showAssembly.aspx?ukey_assembly=562262&ukey_product=4285103

no engine stated, we cant guess this. , gas or diesel?
my wild guess. is bad TPS.

hesitates for instant and the catches up. bad TPS or vacuum leaks.

i had the same car.... what mileage.... 200K?
TPS errors. (its real its a real measured error)
this error is catastrophic, , meaning, not just a tad off,
the FSM covers this in details.
clock spring, the Air bag clock spring? has nothing to do with this.
or do you meant the throttle return spring, (my guess?)
the TPS output pin was discovered to have an illegal high voltage
on the output (you can be sure it idid)
spec:
TP Sensor indicated more than 4.50v for 700 ms.

caused by a bad TPS ground wire, or the output pin cut.
or the TPS internals are cracked in half (bad inside) (i have photos)
its bad TPS or bad wires to it. simple huh?
it will not be a bad ECU. as is on the list; it will not.
The jeep has great cheap TPS to buy ofter market,
on other cars not, and can cost $300 , for them
i connect my potable scope and watch the TPS output while i drive.
and find out if it is really truly bad.... hell the part, costs more than my
scope.!
be happy its not new car with throttle by wire, !!!
or the big V8 , whole new throttle body for $1000

recap. bad TPS, bad wires.

the tps on most cars are calibrated.
if you just thrown on a new TPS and not calibrate it, that is
a big failure.
here are the steps
1 key off
2 remove TPS.
3: put back new.
4:
The TPS is mounted to the throttle body. The throttle shaft end of throttle body slides into a socket in the TPS. The TPS must be installed so that it can be rotated a few degrees. (If sensor will not rotate, install sensor with throttle shaft on other side of socket tangs). The TPS will be under slight tension when rotated.

1. Install TPS and retaining screws.
2. Tighten screws to 7 Nm (60 inch lbs.) torque.
3. Connect TPS electrical connector to TPS.
4. Manually operate throttle (by hand) to check for any TPS binding before starting engine.

adjust the TPS for
0.26 volts at minimum throttle opening (idle)

worst case:
the FSM says it auto calibates
if the new TPS errors,. set it to 1/4 volt at idle.
reset ECU , all DCTs using scan tool
pull battery for 5min neg. lug (backup radio codes first)
put back lug
start engine, drive 25miles or till CEL comes on (failures)

Go to Autozone,they will scan your vehicle and tell you why that light is on.It's free and only takes a few minutes.

This is a common problem with GM's. The TPS sensor goes bad in the throttle body. Throws out a message to service Stabilitrac. Not SO!!!
The kicker is that the whole throttle body has to be replaced because the TPS sensor is actually part of the throttle body!!! Costs around $250.00 for aftermarket.

this could be a serious problem as you stated oil residue in exhaust pipe. You can remove spark plugs and check for oil fouling, this is a sign of bad rings, valve guides or seals. A cylinder leak down test would be your best check at this point to see if there is piston ring damage. If the rings are bad, oil would be burned at higher r.p.m. and may not be noticed at idle. I strongly suggest returning to dealer if under warranty or qualified mechanic as potential for engine failure may be present.

A scan tool is necessary to check the TPS voltage so if tool not available have a local shop or dealer perform this. Otherwise a check engine light may be induced from the mis-adjusted TPS sensor. There is the old school way to check and your going to need a multi meter. Disconnect the wire harness from the TPS and use the multi meter to test the resistance on the TPS, as you turn the throttle up the resistance should go up as a contain value in a smooth readings without any jumps. Good luck and hope this helps, keep me posted be glad to help and why do you think there is a TPS malfunction? 

yes you can take it to a muffler shop and either have it drilled out or replaced. They are bad when they are clogged, so if you are in a state that requires no inspections then I would just have it drilled out to unclog it. it's a whole lot cheaper than the dealer is telling you.

Please be advise that if you drive this and the check engine light is flash on and off. you should not drive it any more till you find the problem because you can cause more damage to the truck if the light is flash. there are many things that could cause this running condition: TPS, EGR, Bad injector, Idle air control and more would need to know codes that are in the computer, engine size 2 or 4 wheel drive, does it have A/C, Cruise, traction control, ABS brakes, then I maybe able to help you
