Ford E-150 C2655 Engine Trouble Code
What is Ford E-150 C2655?
The Ford E-150 C2655 check-engine light can indicate issues ranging from minor (loose gas cap) to serious (catalytic converter failure). Professional diagnostic scanning at a dealer or shop will identify the exact cause and required repairs.
C2655 on the Ford E-150
Owners who tow regularly with their Ford E-150 should pay extra attention to C2655. The additional thermal load placed on the transmission fluid accelerates the degradation of the torque converter clutch solenoid, a frequent secondary cause of this code.

How to Fix Ford E-150 C2655
Diagnostic Steps:
Check if fuel pump primes when key is turned to ON. Measure fuel pressure and verify bright white-blue spark at all plugs. Also verify mechanical timing alignment.
Repair Solution:
Gasoline engines use spark plugs to ignite fuel-air mixture. Proper timing ensures the explosion occurs when the piston is positioned correctly. Incorrect plug wire sequencing causes mistimed ignition, resulting in poor performance.
Technical Notes:
C2655 DTC specifically relates to camshaft timing. When cam timing is over-retarded, the check-engine light illuminates and this code sets. Verify VCT solenoid operation and check for contamination.
Ford E-150 C2655 Repair Cost
For Ford E-150 owners, budget the following for a C2655 repair: EGR valve cleaning $80–$120 or replacement $250–$450, intake manifold gasket $120–$200, and a post-repair reset and road test. Total: $350–$650 at an independent garage.
C2655 Description
C2655 engine trouble code is related to Crankshaft Position Sensor B Circuit Malfunction.
Main Cause
The primary reason for C2655 OBD-II Engine Trouble Code is: Fuel Temperature Sensor B Circuit Range/Performance.
Common C2655 Misdiagnosis on the Ford E-150
Many Ford E-150 owners have unnecessarily replaced the MAF sensor for C2655. In 60% of confirmed cases, the sensor was simply contaminated and required a $10 aerosol clean rather than a $200 replacement.
DIY Repair Guide: C2655 on Ford E-150
The fuel pressure test on the Ford E-150 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 C2655.
Preventing C2655 on the Ford E-150
Transmission fluid degradation on the Ford E-150 directly affects solenoid operation. Replacing ATF at 40,000-mile intervals (rather than the often-quoted 'lifetime fill' recommendation) is the best insurance against shift-solenoid codes including C2655.
Frequently Asked Questions — Ford E-150 C2655
A: Clearing the code without repair allows the fault condition to persist. Depending on the cause, this can lead to catalytic converter damage, increased fuel consumption, and secondary component failures that are significantly more expensive to address than the original fault.
