In all probability not. If you have a check engine light on then you will need to have it scanned for codes. If the code shows a component, such as the TPS, it DOES NOT mean that is defective. It only means the problem lies in that area. That is what you pay a technician to let you know. It is cheaper to know what is the problem, than to throw parts at the car.

Will throttle position sensor cause hard shift?

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.

A failing throttle position sensor will cause idling problems when the car is warm. The failing sensor can also cause the car to stall when idling.

What would be the problem with an 87 Chevy Celebrity hesistating when you hit the gas?

Hesitation can be caused by several things: 1. A faulty throttle position sensor might cause hesitation. 2. A faulty MAP or MAF sensor might also cause hesitation. 3. A problem with the engine control module might cause hesitation.

98 Chevy Cheyenne will start but dies if you give it gas?

The possibilities can be many. It can range from a malfunctuioning fuel pump, to a bad throttle position sensor, to faulty fuel injectors. First I would check the throttle position sensor since this is the cheapest part, and also the easiest to replace. The throttle position sensor tells the computer how much air and fuel to put in the engine. If it is messed up it can cause hesitation, stalling, transmission buckoing, etc...

Where is throttle position sensor 2003 dodge ram?

If it is an 3.7L or 4.7L engine it is on the throttle body mounted on the side. If it is a hemi engine there are two throttle position sensors. The throttle body is electronic. There is a position sensor mounted underneath the battery hidden behind a cover. The accelerator cable goes from the gas pedal to this sensor. This sensor sends info to the PCM (powertrain control mondule). There is also another position sensor inside the electronic throttle body which tells the PCM what position the throttle plate is at. These throttle bodies on the hemi engines become dirty and cause codes like a P2175 and 2106. It will also make the ETC light flash, and cause low acceleration and limp in mode problems. Cleaning this throttle body will correct this.

Bad Throttle Position Sensor

What does a throttle position sensor do?

The throttle position sensor (TPS) keeps the PCM informed about throttle position. The PCM uses this input to change spark timing and the fuel mixture as engine load changes. A problem here can cause a flat spot during acceleration (like a bad accelerator pump in a carburetor) as well as other drivability complaints.the throttle position sensor (tps) tells the computer where you have your foot while driving ( half throttle or quarter ect.)

Can a throttle position sensor keep the engine from starting?

A throttle position sensor might keep the engine from starting. Any number of things can cause a vehicle not to start. The starter and the gas line sensors are also a possible culprit.

What would cause a car not to shift gears when going up a hill then start a clicking noise?

Typical causes would be: -faulty throttle position sensor -faulty accelerator position sensor (if drive-by-wire) -faulty throttle body (if drive-by-wire) -restricted exhaust catalyst or other exhaust restriction -restricted fuel filter -poor fuel quality -floor mat interfering with accelerator pedal operation -overdue for tune-up (gasoline engine only)-ignition timing fault -knock sensor inoperative -false low MAF sensor reading -false MAP sensor reading -DPFE sensor or hoses bad (Ford only) -clogged air filter

What are symptoms of a bad throttle position sensor?

A bad throttle sensor can cause several problems. Symptoms include rough idle, loss of power, and even power surges while driving. .

What cause of early shifting of automatic transmission?

A sensor has failed, and is reporting the wrong value to the transmission controller. Old transmissions: Probably the vacuum modulator or throttle position sensor. Also check the fluid level. New Transmissions: Output speed sensor, turbine speed sensor, throttle-position sensor, fluid pressure sensor, and sensors on the engine.
