This can include stalling when coming to a stop or very low idle after starting, or even stalling if the throttle is quickly pressed (resulting in the throttle body plate opening and closing very quickly).
a faulty tps can set a trouble code in the computer if the voltage value is either not present, sporadic, slow or constant, and this can illuminate your check engine light. 2.
The Throttle Position sensor measures the throttle position, which is controlled by the gas pedal. It is used to determine engine load and if it fails it can cause automatic transmission shifting problems. When a throttle body is not functioning correctly, some noticeable characteristics may be poor or very low idle.
Code P0122 is triggered when your vehicle’s Engine Control Module (ECM) detects that your Throttle Position Sensor (TPS) circuit A is reporting an output voltage that is below its expected voltage. Depending on your vehicle, your TPS lower output voltage limit should be around .
RepairPal.com suggests that a throttle body cleaning costs between $226 and $290. What’s interesting to note is the price of parts: $6 to $12, the low estimate of which is about twice the cost of a can of CRC Throttle Body Cleaner at your average auto parts store.

Once you start to accelerate, there is more load put on the lifters as they try to move faster. If the oil flow is not sufficient, the lifter will not fully pump up and will cause the noise you hear. Change the oil and make sure you use the exact oil viscosity rating specified for your vehicle.
Leave the key off for a moment, turn the key to the “On” position again, wait 3 seconds, and press the accelerator 5 times in 5 seconds. Wait 7 seconds, and hold the accelerator down. The check engine light should start blinking, continue to hold pedal down until it stops blinking. You can then start the car.
If the TPS is not adjusted correctly as evidenced by a 500rpm idle, and hesitation with initial acceleration, unplugging the TPS connector should then cause a correct idle, and a normal acceleration.
Throttle Position Sensor Replacement Cost – RepairPal Estimate. Labor costs are estimated between $54 and $69 while parts are priced between $100 and $130. This range does not include taxes and fees, and does not factor in your specific vehicle or unique location.
