Po 122 problem light on had changed sensor problem not fixed trans not shifting right horrible jurks when it shifts.

P0122 is TPS signal low, which could mean you have a bad TPS, or a fault in the wiring or connector. I suspect a bad Throttle Position Sensor.

Did you test the TPS ( throttle position sensor)?

The automatic transmission uses throttle position sensor to determine position and opening of throttle, and to decide when to shift into gear.
IF throttle position sensor is defective, the car may have problems shifting into one or more gears, and you may also get no error code from OBDII scanner.

The TPS is tested reading volts on the TPS contacts, while someone else from inside the car smoothly press the pedal.

If the TPS is bad, the voltage will not change smoothly, but there will be gaps and peaks in voltage.

If the TPS is ok, then the next step will be checking the transmission shift solenoid pack located in the valve body. This are tested measuring Ohms on solenoids, and cheching if they get powered. This is unlikely the problem, as you would get a P0700 code from TCM.

Finally the TCM (transaxle control module) may be faulty. This may also return no code, as the TCM will think it is doing its job. This fault is also rather uncommon, and can be tested reading voltages on TCM connectors to TPS.

At a glance, from your broad description, you have a faulty TPS.

How to change a throttle position sensor on a 94 ford f150 5.0 4x4

How to Replace a Throttle Position Sensor
(DIY & Save up to $135.75 ) - Time: 2.1 hours

1. Throttle Position Sensor - $ 55.44

1. Scan Tool
2. Screwdriver
3. Multimeter

1. Locate the OBD data link connector (DLC). Refer to your owner’s manual for the specific location.
  • Tip: The OBD-I data link connector is usually located in the engine compartment near the battery or the fuse box. The OBD-II connector (post 1995 cars) is usually located beneath the instument panel next to the steering column.
2. Turn your key to the“ON” position. Do not start the engine.

3. Plug your scan tool into the OBD data link connector. Turn on the scan tool and select the appropriate steps to read the diagnostic trouble code (DTC).


Scanner plugged into OBD-II data link connector.
  • Tip: The OBD-II diagnostic trouble code (DTC) is a 5 character alphanumeric code. The first digit is a letter that indicates the component group, the second digit is OBD mandated or manufacturer specfic, the third digit is a subgroup, and the fourth and fifth digits define the component and basic problem.
  • 4. Locate the throttle position sensor.

  • Throttle position sensor

  • 5. Disconnect the electrical connector from the throttle position sensor.

  • Electrical connector removed
6. Test the resistance of the throttle position sensor (TPS) with a digital multi-meter. If the resistance is out of specifications, the TPS must be replaced.
  • 7. Remove the throttle position sensor.

  • d3a8007.jpg

    Removing sensor mounting screws

    8. Install the new throttle position sensor. Tighten the mounting screws and attach the electrical connector.
  • 9. Erase the diagnostic trouble code (DTC) with the scan tool using the“delete” or“erase” command. Road test your vehicle to see if the check engine light returns.

    Check engine light

  • Tip: If the check engine light returns, repeat the diagnostic process for additional DTCs or take your vehicle to a certified repair shop.
Direct OE replacement

Hope helped with this. Good luck (remember rated this help).

Throttle/Pedal Position Sensor/Switch B Circuit Range Performance

there is no adjustment on these tps's it's a drive by wire system. If you don't know the vehicle, dont post!
there's 2 sensors contained in the pedal sensor, and one on the throttle plate shaft, more often than not, it's the pedal sensor, and if you replaced that, it's the other one or a loose connection. did you reset the computer after replacing the pedal?

You need to test voltage and ground if you have less than 5 volts you have a problem with voltage not a problem with the throttle position sensor you may have gum build up in the throttle plate not allowing the plate to go to the full close positions and that can throw the same code you are getting. Also if you have a reading of .2 ohms or more from battery post to ground or to engine to ground or to engine ground to throttle to ground that could be your problem, after testing these items then next step is testing computer. But try cleaning the throttle assembly plate inside the backside and in the mouth where the plate goes. Also the Wide-open and idle position must be set when replacing the sensor or you will get the same error.
