P1226 Control Sleeve Sensor Malfunction

erro p 1226

Usually this is just a bad wheel bearing assy. Which comes with the speed sensor.. But double check the wiring to the sensor sometimes they can rub against the axle shaft if they come loose and get cut in two..

clean or replace idle control valve

I would say u are safe to assume the trottle sensor is defective or the wiring to the sensor is open or shorted. check the connector for pushed out pins.

Most likely a cam sensor as this is where the fuel injectors get their information from. Check for a bad fuse with your linking error as you may not have a signal at the DLC.
