got no code only happened once, thanks for the suggestion, guess I will be changing throttle body sensor soon
Make sure you follow the procedures to check your existing TPS voltage before pulling off the old one.
CHECKING TPS VOLTAGE
To check the TPS voltage you must have a DIGITAL voltmeter.
1. LEAVE THE THROTTLE BODY MOTOR UNPLUGGED (the small connector on the driver side of the throttle body).
2. Ground the black wire of your meter and poke the probe of the red wire on the meter into the YELLOW wire of the TPS sensor which is the bottom wire on the plug located on the passenger side of the throttle body. You DO NOT need to break the wire to read voltage. The best way to probe the yellow wire is to poke the probe into the plastic harness plug (while it’s plugged in to the TPS). You will need to penetrate the blue insulator the goes around the end of the yellow wire (hidden inside the harness plug) to reach the bare metal end of the yellow wire. Touch the probe to the bare metal end of the yellow wire
3. Turn the ignition to the ON position but do not start the car.
4. Read the meter display. You should see a voltage reading between 1.19-1.31 volts. Write the voltage down.
5. Now install new TPS sensor and repeat 1-4. Try to get as close as possible to the original reading by following the steps below.
ADJUSTING TPS VOLTAGE
1. With your meter still connected, loosen the mounting screws on the TPS sensor and gently rotate it until the desired voltage is achieved. Then tighten the screws.
2. Once the desired voltage is achieved, plug the throttle body motor in.
3. Turn the ignition key to the OFF position, then cycle the ignition key from the ON position 4 times to allow the car to "self check" the throttle body and sensors for proper operation.
If the throttle body voltage and senors are correct then the CHECK ENGINE and FAILSAFE warnings should be gone when you turn the key on for the 4th time..
