Delage 3-litre C2655 Engine Trouble Code
What is Delage 3-litre C2655?
The Delage 3-litre 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 Delage 3-litre
The Delage 3-litre uses a dual-port fuel injection architecture that is sensitive to ethanol content variations. When E10 fuel is substituted with E5, or vice versa, the fuel trim corrections can cross the DTC threshold and store C2655 in the ECU.

How to Fix Delage 3-litre 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:
Disconnected, dirty, or fouled spark plugs commonly prevent proper engine operation. Replace spark plugs every season or 25 hours. Verify proper spark plug gap. If plugs are good, check ignition components: spark plug wires, coils, and ignition module.
Technical Notes:
Parts or components should not be replaced based solely on C2655 DTC. Consult your vehicle service manual for proper diagnostic procedures, possible causes, and required testing before replacement.
Delage 3-litre C2655 Repair Cost
Intercooler hose replacement on turbocharged Delage 3-litre models costs $120–$250 per section. A boost-leak smoke test ($50–$80) is the definitive diagnostic method and will pinpoint exactly which hose or connection is at fault before any parts are ordered.
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 Delage 3-litre
Fuel injector replacement is over-prescribed on the Delage 3-litre for C2655 when the actual fault is a weak fuel pump. Low fuel rail pressure causes lean misfire that looks identical to injector failure in static scan data without a live fuel pressure test.
DIY Repair Guide: C2655 on Delage 3-litre
Replacing the spark plugs on the Delage 3-litre is rated a difficulty 2/5 for home mechanics. The top-mounted plug access on this engine requires a 3/8" extension and a 14mm spark plug socket. Always torque to the manufacturer's specification to avoid cracking the cylinder head.
Preventing C2655 on the Delage 3-litre
Scheduled inspection of the Delage 3-litre air filter every 15,000 miles can prevent the intake restriction that leads to C2655. A blocked filter forces the engine to run rich, stressing the catalytic converter and ultimately storing fault codes.
Frequently Asked Questions — Delage 3-litre C2655
A: Simple fixes like a purge valve or gas cap replacement take under an hour. Sensor replacements typically require 1–2 hours of shop time. More involved repairs like VVT actuators or catalytic converters may require a full day or more.
