Lagonda 2-litre C2727 Engine Trouble Code
What is Lagonda 2-litre C2727?
Lagonda 2-litre C2727 code can indicate a faulty oxygen sensor, which may eventually damage the catalytic converter (repair cost: $2,000–$2,200). Professional diagnosis costs around $200–$210. Oxygen sensors are often straightforward to replace — check your owner's manual for location and instructions. This issue should be addressed promptly to prevent further damage.
C2727 on the Lagonda 2-litre
For Lagonda 2-litre owners, diagnosing C2727 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 Lagonda 2-litre C2727
Diagnostic Steps:
Regarding C2727, carefully inspect the wire harness near the intake manifold bracket, best accessed from below near the oil filter. Look for chafing, pinching, or damaged insulation.
Repair Solution:
Power steering pressure switch monitors system operation. If pressure changes are not detected after calibrated speed transitions, this DTC sets. Verify PSP switch operation and check for circuit opens or shorts.
Technical Notes:
C2727 DTCs can be triggered by upstream issues. For example, a dirty MAF sensor may cause incorrect fuel-trim adjustments, leading oxygen sensors to report mixture problems. Address root causes first.
Lagonda 2-litre C2727 Repair Cost
A fuel pressure regulator replacement on the Lagonda 2-litre runs $180–$320 at a specialist. Fuel system work requires depressurisation procedures, so this is not typically a DIY job. Some workshops include a full fuel injector flow test (value: $80) at no extra charge.
C2727 Description
C2727 engine trouble code is related to Shift/Timing Solenoid Malfunction.
Main Cause
The primary reason for C2727 OBD-II Engine Trouble Code is: Fuel Rail Pressure Sensor Circuit Malfunction.
Common C2727 Misdiagnosis on the Lagonda 2-litre
On Lagonda 2-litre vehicles, the turbo boost solenoid and the MAP sensor feed into the same diagnostic path. C2727 caused by a faulty boost solenoid is sometimes charged to the customer as a MAP sensor replacement, doubling unnecessary parts spend.
DIY Repair Guide: C2727 on Lagonda 2-litre
When replacing sensors on the Lagonda 2-litre, always use anti-seize compound on the thread and dielectric grease on the electrical connector. This simple habit prevents the most common causes of sensor-related callbacks after repair.
Preventing C2727 on the Lagonda 2-litre
The Lagonda 2-litre EVAP system requires the fuel tank breather hoses to be flexible and crack-free. A visual inspection at every oil change prevents the slow vacuum leak that triggers C2727 without any drivability symptom.
Frequently Asked Questions — Lagonda 2-litre C2727
A: Yes. Any stored fault code — including C2727 — 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.
