TPS switch is located on the throttle body(like a carb) and connects to the butterfly valve there. hence the location of the wires.

My name Ilsur, I of Tatarstan , I have a jeep Grand cherokee WJ laredo 1999 4.0 error P0123 I replaced TPS but nothing helps, replaced the clockspring does not help, help me please

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.
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)

P0123 Just put new Tps and it is showing this code now can adjust the TPS?

DTC P0123 - Throttle Position Sensor/Switch A Circuit High Input
This code means that the the car's computer has detected that the TPS (throttle position sensor) is reporting too high a voltage. Were codes deleted after this job? This is a code for TPS voltage high.

The sensor voltage should never be greater than 5volts. It normally reads .5 to .8 volts at idle (closed throttle). The orange and dark blue is the signal wire, black and light blue is the sensor ground, and the violet and white is the 5volt supply wire. You will need to back probe the signal wire to find the value. It is possible the signal or ground wires are open. Or the PCM is faulty.


Hope this helps (remember to rating this free answer).

1999 Dodge/cummins can the P0122 code cause my hard start problem

this obd2 trouble code table can help you understand the meaning of code, for this code, you can try:
Carefully check the throttle position sensor (TPS), wiring connector, and wiring for breaks, etc. Repair or replace as necessary
Check the voltage at the TPS (refer to a service manual for your vehicle for specific information). If the voltage is too low that is indicative of a problem. Replace if necessary.
If recently replaced the TPS may need to be adjusted. On some vehicles the installation instructions call for the TPS to be properly aligned or adjusted, consult a repair manual for specifics.
If there are no symptoms at all, the problem may be intermittent and clearing the code may resolve the issue temporarily. If this is the case then you should definitely check the wiring to be sure it's not rubbing on anything, grounding, etc. The code may come back.

Where is the TPS sensor loocated on a 1999 oldsmobile silhouette van? I am attempting to do this on my own. The van does not accelerate normally when I pull out. Once I am on the freeway or at higher...

Follow the accumulator cable from the firewall to the intake manifold/throttle body air tube.

It will end right next to the TPS.

TPS is a 3 wires electronic unit.

Please rate my answer is it's helpful to you.

Tps location on 1999 camaro

TPS is always connected to one end of the throttle plate shaft It should not be difficult to identify. If you already have the new one the old one is identical. Usually fastened with two small torx screws.

1999 wrangler problem: high idle,and hesitant.

If it was originally scanned by auto zone and they said Throttle Position Sensor (TPS),i would go back and have it scanned again,this will tell you for certain what it is.Try and get the code number and definition written down.If it were TPS again,the sensor itself would need to be replaced unless the cost was prohibitive,or the wires to and from the sensor and PCM (vehicle computer),ohms checked for continuity first.Eliminating the wires leaves 2 entities in the circuit,the PCM or the TPS.Checking circuits is costly in labor dollars.Good luck.
