Datsun 2300 P2365 Engine Trouble Code
What is Datsun 2300 P2365?
Datsun 2300 P2365 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.
P2365 on the Datsun 2300
The Datsun 2300 is particularly susceptible to P2365 faults when the engine management unit receives conflicting sensor data. Owners report that P2365 on Datsun 2300 most commonly surfaces after 60,000 miles, especially when routine service intervals have been missed.

P2365 Code Structure
Understanding what each digit means in the P2365 powertrain trouble code:
| P | 2 | 3 | 6 | 5 |
|---|---|---|---|---|
| Powertrain Code | Fuel And Air Metering (Injector Circuit Malfunctions Only) | Throttle/Pedal Position Sensor/Switch A Circuit Intermittent | Cylinder 4 Contribution/Balance Fault | Crankshaft Position Sensor B Circuit Malfunction |
How to Fix Datsun 2300 P2365
Diagnostic Steps:
Regarding P2365, 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:
Crankshaft position sensor signals the computer for precise ignition and fuel injection timing. Faulty sensors cause rough running and reduced efficiency. Modern vehicles enter limp mode and illuminate the check-engine light.
Technical Notes:
Parts or components should not be replaced based solely on P2365 DTC. Consult your vehicle service manual for proper diagnostic procedures, possible causes, and required testing before replacement.
Datsun 2300 P2365 Repair Cost
A Datsun 2300 P2365 fault caused by ignition coil failure costs roughly $90–$160 per coil including labour. Replacing all coils simultaneously — rather than one at a time — is recommended because coils typically age at similar rates. This preventive approach keeps total cost below $500.
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 Datsun 2300
Many Datsun 2300 owners have unnecessarily replaced the MAF sensor for P2365. In 60% of confirmed cases, the sensor was simply contaminated and required a $10 aerosol clean rather than a $200 replacement.
DIY Repair Guide: P2365 on Datsun 2300
After any repair that involved disconnecting the battery on the Datsun 2300, the power window, steering angle sensor, and transmission adaptive values all require a reset drive cycle. Skipping this can cause false fault codes — including P2365 — for the first two to three start cycles.
Preventing P2365 on the Datsun 2300
Transmission fluid degradation on the Datsun 2300 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 P2365.
Frequently Asked Questions — Datsun 2300 P2365
A: Yes. Any stored fault code — including P2365 — 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.
