How To Bypass Crank Position Sensor: Can It Be?

How To Bypass Crank Position Sensor

The importance of the crankshaft position sensor cannot be neglected. The Crank Position Sensor is a small electronic device that is used to measure the position of the crankshaft in an engine. This information is then used by the engine control unit to adjust the timing of the ignition and fuel injection system.

The Crank Position Sensor is typically located on the side of the engine block near the crankshaft pulley. It is one of the principal sensors present in the vehicle, due to which a car runs smoothly and efficiently.

With a bad crankshaft position sensor, your engine check light will be lit, indicating some issues with the sensor. If the issue is not fixed in time, it can cause the sensor to deteriorate gradually, and you will end up with a faulty sensor. If your car has an issue with the crankshaft position sensor and you’re wondering whether it can be bypassed, this page has the answer.

Without a crankshaft position sensor, the vehicle will not start at all. Therefore, you cannot bypass the crankshaft position sensor.

Initially, with a bad crankshaft position sensor, you will experience difficulty starting your vehicle, and it will be consuming relatively more fuel. But as the condition worsens, your engine will start malfunctioning, and your vehicle won’t start.

A lot of people ask the question of how to bypass the crankshaft position sensor. Instead, they should ask whether the crankshaft position sensor can be bypassed or not.

The answer is NO.

With a bad crankshaft position sensor, the ECU won’t see the crankshaft moving. As a result, the ECU will not allow fuel to enter the combustion chamber for combustion.

Hence, the engine will not start. You have the only option left is to replace the bad crankshaft position sensor with a good one to start the car.

The ECU needs a crankshaft signal to start the vehicle. If there is no crankshaft signal, there would be no signal sent forward by the crankshaft position sensor to the car’s Electronic Control Unit (ECU).

The ECU will assume that the engine is not cranking and will not produce a spark in the engine. As a result, the car will not start.

Thus, if you encounter that the crankshaft position sensor of your vehicle is not working correctly, replace it immediately. You can either replace it yourself or take assistance from a reputable auto repair shop.

So, the bottom line is the crankshaft position sensor cannot be bypassed if it goes bad.
