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)
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
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.
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.
- Install TPS and retaining screws.
- Tighten screws to 7 Nm (60 inch lbs.) torque.
- Connect TPS electrical connector to TPS.
- 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)
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)
