year, make, model, engine size?

The TPS is the Throttle Position Sensor. It is typically located on the throttle body directly across from where the throttle cable is attached. It also typically has a three wire round connector.

again, posting the vehicle information will help us better help you!

Torque converter won't lockup on 2006 TDI Rodeo, can this be caused by faulty TPS on throttle body?

Torque converter lockup normally only happens in high gear and when engine is not under heavy load. Sounds as if yours is running so poorly it should not go into lockup. Run compression test to check for blown head gasket.

Symptoms of a bad tps

old post. but....
a great question, but on a tracker , the TPS , has 2 parts inside
cascaded as one part. so that makes answers harder.
the tests are here.

  1. idle switch bad, means, idle never regulates.
  2. end idle side.
  3. throttle angle side, is complex. (as seen in scan tool)
  4. it detects drivers fast right foot actions and enriches fuel this prevents the hesitation, when you accelerate. if bad it does just that. but does still have full power up hills (after small hesitation) due to the MAF sensor seeing reality and correcting the TPS (errors) see?
  5. the TPS also triggers. cut fuel mode when you decelerate,
  6. and triggers cut off of EGR and .
  7. and triggers , anti snap your next mode , when you decelerate too fast it adds air via the ISC to prevent violent Deceleration.
  8. I told you it was complex the FSM book from Suzuki and GEO both stated all that. on the TPS page.

get the Factory Service manual, real, and see those pages.

No power when going up hill

I have seen many pass though my shop, these are some what known for this ! There's a 95% chance it is your TPS, throttle positions sensor, now the other 5% has also been there Crankshaft Sensor and IAC, are you doing you doing the work yourself ? If you are, it would help if you get a repair manual for your car. Because then you can follow the test for each of these, you would also need a multi meter to test with. On a scale of 1~5 with 5 being the hardest, I would say it's a 2.What you need the repair book for is the voltage to test for on each of these sensors.

Misses badly when accelerating or under a load. shift out of overdrive on incline due to power loss

Have you checked for codes?

Any dash lights lite?

Any testing done so far?

Have to do something then tell us,can't
guess and don't have the car to drive.

You most likely have ignition issues,if the
engine is hot & your going up hills

It down shifts based on shift strategy & vehicle
speed & many pcm inputs from sensors

Could be egr issues

Do you ever do any preventative maintenance?

Acts like it is not getting enough fuel when going up hills. have replaced fuel filter but still having trouble. 2000 Ford Expedition 5.4l engine

Fuel is controlled by the O2 Sensors
Where they replaced at 100,000 miles?

Check fuel pressure on engine fuel rail,
with a gauge

Clean MAF Sensor

1998 Dodge Ram 4X4 Quad 5.9L Auto. When accelerating slowly, shift fine until up to a cruizing speed, then keeps shifting up & down like into/out of a passing gear. Going up hill under a slight load...

Mr. dodge ram, with the 46re trans the pcm needs a signal from the tps sensor to monitor throtlle opening, accel and decel, what has happened the tps has a worn out spot in cruise area, hence the down shift, uphill is fine because your past the worn out spot, replace your tps sensor, its mount on left side of throtlle body , 2 screws, 1 connecter, and its out, when done turn key on, eng off, step on gas pedal 6 times slowly, then turn off key, this will help set min tps setting, GOOD LUCK RDJRP

Nissan Terrano Chugging

When you are going up a hill, the engine is under an incresed load - requiring more fuel and spark, so I'd first check all of the ignition related items (Plugs/wires/cap/rotor), and it isn't a bad idea to replace the fuel and air filters if you haven't in a while. Once those are checked, it is very very common for a TPS (Throttle Position switch) to develop "dead spots"; where under accelleration they cause a "chugging", which sometimes is quite unnoticable - unless/until vehicle is under a load ( eg. driving up a hill). A new TPS can be installed and set with a multi-meter - probes attached to the proper terminals, and have the output voltage set at .47V to .50 V at idle (Closed throttle). I'd bet this is the cause, as they usually do not set a DTC (Code - Service Engine light) . It isn't 100% for sure, an air flow meter and/or other things can cause this type thing as well (also a weak spark or coil, etc), but highly unlikely - other malfunctioning parts often set trouble codes as well, and usually either malfunction or they don't. Hope this helps and if you find anything else - please let me know.
