Zagato Zeta P2365 Engine Trouble Code
What is Zagato Zeta P2365?
Zagato Zeta P2365 indicates potential catalytic converter failure. If completely failed, your vehicle may not run properly and fuel economy will suffer significantly. Average replacement cost is $2,000–$2,140. This repair requires professional service and should not be delayed.
P2365 on the Zagato Zeta
On high-mileage Zagato Zeta examples, P2365 is often the first sign of a failing fuel pressure regulator. Residual fuel pressure bleeds off overnight, causing lean-start conditions that the ECU registers as a fault at the next cold start.

How to Fix Zagato Zeta P2365
Diagnostic Steps:
The catalytic converter has oxygen sensors before and after it. When warm and in closed-loop mode, the upstream O2 sensor reading should fluctuate, while downstream should remain steady.
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:
P2365 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.
Zagato Zeta P2365 Repair Cost
ECU software update for the Zagato Zeta to resolve the P2365 calibration bug is performed free of charge at a franchised Zagato dealer under the technical service bulletin programme. Always confirm the ECU part number and current flash version before spending money on sensors.
P2365 Description
P2365 engine trouble code is related to Crankshaft Position Sensor B Circuit Malfunction.
Main Cause
The primary reason for P2365 OBD-II Engine Trouble Code is: Throttle/Pedal Position Sensor/Switch A Circuit Intermittent.
Common P2365 Misdiagnosis on the Zagato Zeta
When Zagato Zeta presents P2365 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: P2365 on Zagato Zeta
The Zagato Zeta EVAP purge solenoid valve is accessible without lifting the vehicle — it is mounted on the intake manifold and secured by a single bolt and a vacuum hose clip. DIY replacement is rated 1/5 difficulty and takes approximately 20 minutes.
Preventing P2365 on the Zagato Zeta
The Zagato Zeta heat shield over the exhaust manifold protects the nearby sensor wiring from radiant heat damage. Inspect it for cracks or displacement at every brake service. A $15 replacement shield can prevent $300+ wiring loom repairs.
Frequently Asked Questions — Zagato Zeta P2365
A: Yes. A weak battery causes voltage drop during cranking that confuses the ECU and can store a range of fault codes. Always rule out battery and charging system health before diagnosing sensor-related codes.
