My car , The Tps does not move much even when rev goes to 2000, it seems to stay at that figure of 3.92% from obd reading whether it revving or not. It only moves a bit sometimes, is this normal? If the Tps is 3.92% at idle when the engine is revved to 2000 or 3000 should the Tps move as well ?as mines does not move much , how much should it move to approx from the idle value of 3.92%?at idle car is 823rpm , hence 2000 rev should at least get tps to 15-30%. Does starting tps at idle of 3.92% with rpm 823 sound normal if not what value should the tps start at approx?

Could anyone confirm if my suspicions are right that the TPS sensor is not working hence the reason why the reading is not moving much from 3.92% when pressing accelerator? If I am correct the car is still functioning as normal I am not depressing the gas pedal more than my other cars. What could be at fault here apart from the tps , does the oxygen sensor or iat or map or even the camshaft sensor or crankshaft sensor have any effect on the TPS. Does the tps affect any of the other sensors such as crankshaft or camshaft? Thanks

Is the car functioning correctly? If so I'd be tempted to ignore it depending on age as some OBD values are often useless on older incarnations of the standard.

Car is functioning well but other obd values look sensible hence a bit concerned as to why the tps look strange and wanted to get others view on it ? Thanks
