How do I reset my electronic throttle control on my jeep?

Resetting Your Electronic Throttle Control

  1. Step 1 – Make sure the accelerator pedal is fully released. …
  2. Step 2 – Turn the ignition on and then turn it off. …
  3. Step 3 – Turn the ignition on again for 7 seconds and then press the gas pedal five times before releasing for 5 seconds.

How do I reset my throttle position sensor?

The easiest way to reset your throttle position sensor is to unhook the negative cable from your battery for up to five minutes or to remove the fuse for your engine control module.

Do you have to reset computer after replacing throttle position sensor?

Do You Have To Reset Computer After Replacing Throttle Position Sensor? Once the throttle body has been replaced, your engine will eliminate the pending code by detecting any engine light on and the issue going away. The ECM (computer) might reset itself if a hard permanent code was used in it.

How do you test a throttle position sensor on a Jeep?

Take the butterfly shaft and manually turn it. As you turn it, you should get a gradual count on the meter upwards to five volts. If the volts fluctuate backwards or forwards erratically, then you know you have a faulty TPS.

How do you reprogram a throttle body?

Turn the ignition switch on and wait 3 seconds. Immediately after the 3 seconds, the accelerator pedal must be pressed and released 5 times within 5 seconds. Wait 7 seconds and fully press the accelerator pedal and hold for approximately 20 seconds until the check engine light stops blinking and stays on.

What happens if you disconnect throttle position sensor?

What Happens If You Disconnect Throttle Position Sensor? TPS, as we call it, is the most important sensor in a car that is used to ensure gas and temperature doesn’t reach zero. Without it, the system cannot predict what’s happening with gas and temperature.

How do I fix code P0123?

What repairs can fix the P0123 code?

  1. Repairing or replacing the TPS connector for shorting.
  2. Repairing the wiring short as necessary.
  3. Replacing the TPS with a new sensor.

How do you test a throttle position sensor?

Testing it involves grounding the connectors’ terminals as you put the multimeter probe on black to negative and red to positive. Make sure the throttle is fully closed by turning the key without starting the vehicle. Then read the voltage. The TPS voltage should be between .

Does a throttle position sensor need to be calibrated?

Once you have fitted a Throttle Position Sensor, or TPS, you will need to calibrate it from within MEITE. First, be sure you have correctly wired, and assigned the throttle sensor signal input to “TPS Raw” in the Analog Settings.

Can you drive without a TPS sensor?

The TPS or Throttle Postition Sensor tells the ECU how far the throttle is open, thus how much fuel is demanded. You will still be able to drive without a TPS, though not very well. The ECU will see a lean condition from the o2 once to open the throttle and it will atempt to richen it up.

What is code P1121?

OBDII code P1121 is Throttle Position Sensor Circuit Intermittent High Voltage. If you have changed it recently it could be out of adjustment or faulty.

What can cause a TPS code?

The voltage of the throttle position sensor can drop below the expected range for several reasons, including the following:

  • A loosely-mounted throttle position sensor.
  • Electrical short on the sensor circuit, either to the ground or to another wire.
  • Faulty sensor.
  • Faulty throttle position switch.
