Ford Excursion C1396 Engine Trouble Code
What is Ford Excursion C1396?
When Ford Excursion C1396 code appears, first check your gas cap. Pull over safely, ensure it is tight, and inspect for cracks. A loose or damaged gas cap affects fuel-system pressure and emissions. A replacement cap costs about $3–$10. This simple fix can resolve the code and improve fuel economy.
C1396 on the Ford Excursion
Transmission-mounted speed sensors on the Ford Excursion share a ground path with the engine control module. A corroded ground point on the transmission bell housing generates electrical noise that the ECU misinterprets as a C1396 fault condition.

C1396 Code Structure
Understanding what each digit means in the C1396 chassis trouble code:
| C | 1 | 3 | 9 | 6 |
|---|---|---|---|---|
| Chassis Code | Fuel And Air Metering | Throttle/Pedal Position Sensor/Switch A Circuit Intermittent | Crankshaft Position Sensor A Circuit Malfunction | Ignition Coil A Primary/Secondary Circuit Malfunction |
How to Fix Ford Excursion C1396
Diagnostic Steps:
Oxygen sensors measure exhaust gas oxygen content to optimise air-fuel ratio. This optimisation improves fuel economy and reduces emissions. Sensors degrade over time and require periodic replacement.
Repair Solution:
Verify all electrical connections are clean and tight. Check for damaged wiring, especially in high-heat or high-vibration areas. Use manufacturer wiring diagrams for accurate diagnosis.
Technical Notes:
C1396 on electronically controlled automatic transmissions relates to shift solenoid operation. The solenoid actuates hydraulic circuits controlling clutches or bands for gear changes.
Ford Excursion C1396 Repair Cost
Replacing the lambda (O2) sensor wiring loom section on the Ford Excursion costs $90–$160 at a body shop or auto-electrician. This is far cheaper than replacing the sensor itself when the sensor is otherwise functional — always inspect wiring before condemning sensors.
C1396 Description
C1396 engine trouble code is related to Ignition Coil A Primary/Secondary Circuit Malfunction.
Main Cause
The primary reason for C1396 OBD-II Engine Trouble Code is: Throttle/Pedal Position Sensor/Switch A Circuit Intermittent.
Common C1396 Misdiagnosis on the Ford Excursion
When Ford Excursion presents C1396 with a concurrent coolant temperature DTC, technicians sometimes replace the thermostat rather than the coolant temperature sensor (CTS). The CTS is a $15–$25 component; the thermostat job carries 1–2 hours of additional labour.
DIY Repair Guide: C1396 on Ford Excursion
The fuel pressure test on the Ford Excursion requires a Schrader-valve type fuel pressure gauge ($25–$40) connected to the fuel rail test port. With the ignition ON (engine off), pressure should hold above 30 PSI for two minutes. A rapid drop confirms a leaking injector or failing regulator as the root cause of C1396.
Preventing C1396 on the Ford Excursion
Verify that the Ford Excursion engine air box lid clips are fully seated after any air filter service. An unsealed air box is a direct path for unmetered air past the MAF sensor and is an extremely common — and extremely embarrassing — cause of C1396.
Frequently Asked Questions — Ford Excursion C1396
A: Temporarily clearing C1396 can help determine whether it is intermittent or persistent, but it does not fix the underlying fault. The code will return if the problem is still present. Do not clear codes just before an emissions test without a proper drive cycle.
