U1009 FORD Possible Causes
- Faulty / intermittent ignition module
- J1850 / SCP Bus wiring intermittently open, shorted to power or ground
- Faulty / intermittent connection at the Powertrain Control Module (PCM)
- Faulty EGR Sensor
How do I fix code U1009 FORD?
Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins.
Tech Notes
- This is typically an electrical wiring connection issue, either at the engine controller or at the sensors being monitored by the manufacturer.
- It can occur if:
- The wrong EGR sensor is installed on the vehicle. Verify with the manufacturer for the latest.
- A bad ignition module is present.
Cost of diagnosing the U1009 FORD code
The cost of diagnosing the U1009 FORD code is 1.0 hour of labor. The auto repair labor rates vary by location, your vehicle’s make and model, and even your engine type. Most auto repairs shops charge between $75 and $150 per hour.
When is the code detected
When the PCM is unable to communicate with any other controller on the bus network at any time while the ignition switch is in the “Run” position.
Possible Symptoms
- Engine Light ON (or Service Engine Soon Warning Light)
- Check Trac Light / ABS Light On
- Bucks at highway speeds
U1009 FORD Description
This is a manufacturer-specific fault code and can be used for several different faults, depending upon what the manufacturer wants to use it for. The Powertrain Control Module (PCM) communicates over the Serial Communication Protocol (SCP) bus network or J1850 bus. This is a medium-speed bus communication system and is fault-tolerant, which means any type of intermittent/loose connection at these controllers will cause this code to set in memory, but will still operate, provided a data path is available. When the PCM is unable to communicate with any other controller at any time while the ignition switch is turned on, code U1009 will set. This is the typical reason for this code to set.
