Lancia Ecv C2655 Engine Trouble Code
What is Lancia Ecv C2655?
The Lancia Ecv 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 Lancia Ecv
For Lancia Ecv owners, diagnosing C2655 correctly requires ruling out a faulty camshaft position sensor before replacing more expensive components. The sensor wiring harness on this model runs close to the exhaust manifold and is prone to heat-related insulation damage.

How to Fix Lancia Ecv 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:
Firing order is engineered to minimise vibration. Altering firing order results in mistimed ignition and poor engine operation. Consult vehicle-specific repair manual for correct firing order.
Technical Notes:
C2655 on electronically controlled automatic transmissions relates to shift solenoid operation. The solenoid actuates hydraulic circuits controlling clutches or bands for gear changes.

ECU software update for the Lancia Ecv to resolve the C2655 calibration bug is performed free of charge at a franchised Lancia dealer under the technical service bulletin programme. Always confirm the ECU part number and current flash version before spending money on sensors.
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 Lancia Ecv
The Lancia Ecv purge valve for the EVAP system is located in an area prone to heat damage. It is often overlooked in favour of replacing the carbon canister ($120–$200) when the valve itself ($25–$50) is the failed component for C2655.
DIY Repair Guide: C2655 on Lancia Ecv
Clearing C2655 on your Lancia Ecv with a basic OBD-II reader ($20–$40) is straightforward: plug the reader into the diagnostic port under the dashboard, read the stored code, and clear it. If it returns within one drive cycle, the underlying fault is still present and requires attention.
Preventing C2655 on the Lancia Ecv
After any fuel system repair on the Lancia Ecv, always perform a fuel-trim reset and adaptation drive. Skipping this step leaves the ECU operating on pre-repair learned values, which can generate false C2655 alerts for weeks after the fix.
Frequently Asked Questions — Lancia Ecv C2655
A: Yes. Any stored fault code — including C2655 — will cause an automatic failure in most OBD-II based emissions tests. The code must be resolved and the vehicle must complete a full OBD drive cycle with no new codes before the test.
