Will an engine run with a bad crank sensor?
An engine with a bad crankshaft position sensor may run, but it will likely experience several performance issues. Here are some common crank sensor problem:
- Engine Stalling: The engine might stall unexpectedly, both at idle and while driving.
- Hard Starting: You might have difficulty starting the engine, or it may take longer than usual to start.
- Poor Performance: The engine may run roughly, misfire, or have poor acceleration.
- Check Engine Light: The “Check Engine” light will likely illuminate on your dashboard.
- Reduced Fuel Efficiency: The engine might consume more fuel than usual due to improper ignition timing and fuel mixture.
While the engine might still run with a faulty crankshaft position sensor, it’s not advisable to drive it in this condition. Ignoring the issue can lead to further engine damage and potentially leave you stranded.
How do I reset a crank sensor?
To reset a crank position sensor, you’ll typically need to use an OBD-II scanner to clear any stored trouble codes and perform a relearn procedure. Here are the general steps:
- Connect the Scanner: Plug your OBD-II scanner into the diagnostic port of your vehicle – Vehicle Help.
- Turn on the Ignition: Turn the ignition to the “ON” position without starting the engine – Vehicle Help.
- Enter the Menu: Navigate to the “Service” or “Special Functions” menu on your scanner.
- Select Crankshaft Relearn: Look for an option related to “Crankshaft Relearn” or “Crankshaft Pattern Clear” and select it.
- Follow Instructions: Follow the on-screen instructions provided by the scanner. This may involve starting the engine, idling it, and performing specific actions like accelerating to a certain speed and then decelerating.
- Complete the Process: Once the relearn process is complete, the scanner will confirm that the relearn is successful.
It’s important to follow the specific instructions for your vehicle model, as the process can vary. If you’re unsure, consulting your vehicle’s service manual or seeking help from a professional mechanic can be beneficial.
