The timing of calibrating a sensor is important, so you might need to keep a timer handy when you follow these steps. More seriously, there will be a major carbon buildup inside the engine and the exhaust system, which can lead to major engine problems. The ECU will then provide a value that the TPS could not give (since it is unplugged). From there the ECU knows how much air is in the system so it can adjust the fuel injection. A throttle position sensor is a small electronic device that measures the angle of the throttle valve. Some cars may burp when their TPSs are unplugged while the engine is running. Touch the negative probe on the multimeter to the TPS's negative wire tab, and the positive probe to the positive tab. The Throttle Position Sensor can still allow your car to run. In summary. Crankshaft Position Sensor [Symptoms, Location, Replacement]. Some car models can burp when the throttle position sensor is disconnected when the engine is active.
