What are the effects of a faulty left rear wheel sensor on the car?

Once the wheel speed sensor is indeed damaged, it not only causes a certain deviation in the speed display on the dashboard but also leads to unstable engine idle and reduced acceleration performance. Secondly, when the vehicle starts or decelerates to stop while driving, it is easy to experience a momentary pause phenomenon. Relevant information about the intake pressure sensor is as follows: 1. Introduction: The intake pressure sensor (Manifold-Absolute-Pressure-Sensor), abbreviated as MAP. It connects to the intake manifold via a vacuum tube, sensing the vacuum changes inside the intake manifold as the engine operates at different speeds and loads. These changes are then converted into voltage signals through internal resistance changes in the sensor, which the ECU uses to adjust fuel injection and ignition timing. 2. Working principle: The intake pressure sensor detects the absolute pressure in the intake manifold behind the throttle. Based on the engine speed and load, it detects changes in the absolute pressure within the manifold, converts these into signal voltage, and sends it to the engine control unit (ECU). The ECU then uses this signal voltage to control the basic fuel injection amount.
