Crankshaft position sensor problems result in inaccurate readings from the crankshaft sensor, which could lead to a host of engine problems. It’s best to replace a damaged crankshaft position sensor as soon as possible. Visit Auto Parts Warehouse for a high-quality, replacement crankshaft position sensor right here: https://bit.ly/2xXNPeP
What Does a Crank Position Sensor Do?
The Crankshaft Position Sensor (CKP) is an electronic engine device that registers the rate at which the crankshaft spins and tells the Engine Control Unit (ECU) the position of the crankshaft to regulate ignition, engine timing, and fuel injection.
Signs of a Bad Crankshaft Sensor
- Difficulty in starting the engine – A faulty crankshaft position sensor can cause your vehicle to have starting issues. The car will either have intermittent starting problems or it will not start at all.
- Car stalling – A bad crankshaft position sensor can also cause the crankshaft signal to be cut off while your engine is running, which could result in your car stalling.
- Engine Light comes on – When your crankshaft position sensor starts to go bad, the computer will detect that it’s having problems and the Check Engine light will turn on. Take note, however, that the Check Engine light may also turn on due to other issues, so it’s highly recommended to have your engine scanned for trouble codes.
Causes of a Bad Crankshaft Position Sensor
- Excessive heat – Heat built-up in your engine can melt the plastic casing and damage the crankshaft sensor.
- Faulty wiring harness – Loose wiring, oil or debris can cause incorrect voltage, ground or return circuit problems that can lead to wiring harness problems. This voltage disruption or wear and tear on the wiring may cause the crankshaft sensor to go bad.
- Damaged wheel and pin – The CKP measures the magnetic pulses created by a toothed wheel or series of pins. If either of these two is broken, it will disrupt the pattern of the pulses and may transmit incorrect impressions of the crankshaft’s speed. This will “confuse” the crankshaft position sensor and damage it in the process.
How to Replace the Crankshaft Position Sensor
Step 1: Disconnect your car battery to prevent shock or damage to your car’s electronic panel.
Step 2: Locate the crankshaft position sensor. Its location will vary depending on the vehicle’s year-make-model, so it’s best to refer to your vehicle’s manual to determine the exact location and save time.
Step 3: Remove the CKP. Disconnect the wire harness from the sensor. Mind the wires’ position as you will have to reattach them in the same order when you install a new CKP.
Pry out the bolt with a socket wrench then remove the damaged CKP and replace it with a new one. Simply place it in the exact same slot. You will also be needing a fresh O-ring (mechanical gasket) when reinstalling it as the old one can’t be reused.
Step 4: Reattach the wiring harness in the same order. Once done, the unit will lock into place. If it doesn’t lock, use a paper spacer for manual adjustment.
Step 5: Reconnect your car battery.
