Car starts will not accelerate, code reader says Code DTC 22 Throttle Position Low


Well code 22 means the signal coming from the TPS is too low. That usually means an open circuit between the sensor and the engine computer. The computer sends a 5 volt signal to the sensor and reads what comes back to the computer. Its possible the sensor is way out of adjustment, but more likely a broken wire or connector between the sensor and computer. You would need a scanner to "see" the data stream from the sensor to know for sure.

Switch For check engine light


There is no switch for the Check Engine Light!
The ECM turns the light on when a Diagnostic Trouble Code is set!
The light can be turned off with a Diagnostic Scanner when the code is retrieved but will return if the problem isn't repaired!

Advanced Auto Parts and Auto Zone will scan it for Free,I'd find out what the codes are and go from there!

My buick regal 2003 wont excelerate it starts


It may be the throttle position sensor. You should have a check engine light on in your dash. You will need to have someone plug a OBD II reader in and retrieve the code.
You can spend a LOT of money just putting in one part after another.
Please let me know what you find.

Why is the check engine light on and idle problem?


Could have a bad injector or PSM problem. When idle is bad start pulling each spark plug one at a time , if no change then thats the bad cylinder. Could be a spark plug too. Buy a spark plug wire puller to do this job (plastic only and only use one hand)

Low voltage tps senser.


Not likely getting a bad TPS.Your TPS runs off a 5volt reference wire.Using multimeter with key on engine off Check to make sure you have your 5volt reference check for any deformed terminals or broken wires inside insulation.
