2008 Ford Focus Crank Sensor
One of the most vital parts of your ZETEC engine, the Focus crank sensor is a common cause when your Focus won't start. This direct fit variable resistance style crank angle sensor is a direct fit for your 2.0 liter or 2.3 liter engine. The Focus crank sensor is easy to replace once you have access to the front of your engine.
Designed for a plug and play installation, this Focus crank sensor is tested to ensure proper operation. Each sensor is bench tested to ensure proper identification of the crankshaft position. This sensor sends the signal as a resistance value to the ignition control module.
When your Focus is turning off randomly or takes a long time to start, you can easily test the operation and function of your Focus crank sensor. This will require you to use a digital multimeter to measure the voltage coming from this sensor to your engine computer.

When this Focus crank sensor starts to go out, there's several common Focus issues you will see. Some of these can range from annoying to highly dangerous. For this reason when you have a OBDII Diagnostic Trouble code for your crank sensor, you should not drive your Focus.
Test the Focus crank sensor first and replace it before driving. Of course if you have a stored OBDII diagnostic trouble code, you will need a scan tool to clear your Focus check engine light. Without the proper crank sensor signal from your Focus, your Ford ignition control module or engine control module won't know how to operate your engine.

- Focus hard start condition
- ZETEC intermittently shuts off
- Bad fuel economy
