How to Clean the Throttle Position Sensor? – Throttle position sensor refers to a sensor that monitors the throttle position in an internal combustion engine. The throttle position sensor is located inside the throttle body, which may require maintenance and cleaning to maintain normal function. Not many believe that this cleaning process can prolong the life of the sensor, but in my opinion, it is wrong, and let’s look at the following simple explanation about cleaning the TPS sensor.
Throttle position sensors can clog due to crankcase vapors. These vapors commonly pass through the throttle body when reintroduced into the combustion process and can deposit oily residue on the throttle plate facilitating the accumulation of sludge.
How to Clean the Throttle Position Sensor?
A throttle position sensor refers to a sensor that monitors the throttle position in an internal combustion engine. The throttle position sensor is located inside the throttle body, which may require maintenance and cleaning to maintain normal function.
We can clean the throttle body by using carburetor fluid and a clean cloth to remove light sludge. If heavy sludge buildup is a problem, we have to remove the throttle body, then clean it with solvent and let it dry. During this process, we must not clean the throttle position sensor due to possible contamination or wire damage. The best way to preserve the sensor is to remove and replace it after cleaning is complete.
Symptoms of Throttle Position sensor malfunction
So, here are the symptoms that arise due to a faulty or malfunctioning throttle position sensor, including:
There is a delay in vehicle acceleration
We can recognize this when we press the gas pedal, where your vehicle should immediately accelerate responsively, but the time between after the gas pedal is pressed and the acceleration of your vehicle’s speed does not run spontaneously.
There is an increase in engine RPM by itself
If when you are driving your vehicle and suddenly the engine RPM increases by itself, it is one of the characteristics of the TPS sensor malfunction.
Difficult Transmission Gear Shift
If the TPS sensor is not working properly so it cannot provide accurate information on the position of the accelerator valve opening on the throttle body to the ECU.
It will have an impact on the disruption of the transmission system, especially if your vehicle uses an automatic transmission where the gear shift when increasing or decreasing speed does not work as it should.
Difficult Starter Or Long Starter Time (After the engine is turned off).
One DTC Appears
One of the DTCs appears, including:
- P0121 : TP Sensor Circuit High Voltage (TP Sensor Circuit High Voltage)
- P0122 : TP Sensor Circuit Low Voltage (TP Sensor Circuit Low Voltage)
- P1121 : TP Sensor Signal Lower Than Expected (TP Sensor Signal Lower than Expected)
- P1122 : TP Sensor Signal Higher Than Expected (TP Sensor Signal Higher than Expected)
