Gaz M-20 P262E Engine Trouble Code
What is Gaz M-20 P262E?
With Gaz M-20 P262E, you may drive for several weeks with a malfunctioning MAF sensor, but expect decreased fuel economy and eventual stalling. Shop replacement costs $240–$400 depending on vehicle. The labour is straightforward, with most cost from the part itself.
P262E on the Gaz M-20
For Gaz M-20 owners, diagnosing P262E 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 Gaz M-20 P262E
Diagnostic Steps:
Poor running symptoms align with MAP sensor malfunction. In some cases, a faulty MAP sensor will not trigger a code. The issue may represent separate wiring concerns requiring individual diagnosis.
Repair Solution:
Excessive air inflow may result from vacuum leaks, dirty sensors, or EGR valves not closing properly. Insufficient fuel can stem from dirty injectors, clogged filters, weak fuel pump, or leaking pressure regulator.
Technical Notes:
P262E 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.
Gaz M-20 P262E Repair Cost
For Gaz M-20 owners, budget the following for a P262E repair: EGR valve cleaning $80–$120 or replacement $250–$450, intake manifold gasket $120–$200, and a post-repair reset and road test. Total: $350–$650 at an independent garage.
P262E Description
P262E engine trouble code is related to System Malfunction.
Main Cause
The primary reason for P262E OBD-II Engine Trouble Code is: Fuel Temperature Sensor B Circuit Range/Performance.
Common P262E Misdiagnosis on the Gaz M-20
The Gaz M-20 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 P262E.
DIY Repair Guide: P262E on Gaz M-20
The fuel pressure test on the Gaz M-20 requires a Schrader-valve type fuel pressure gauge ($25–$40) connected to the fuel rail test port. With the ignition ON (engine off), pressure should hold above 30 PSI for two minutes. A rapid drop confirms a leaking injector or failing regulator as the root cause of P262E.
Preventing P262E on the Gaz M-20
After any fuel system repair on the Gaz M-20, 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 P262E alerts for weeks after the fix.
Frequently Asked Questions — Gaz M-20 P262E
A: Contaminated or low-octane fuel can temporarily trigger P262E through knock retard and lean/rich excursion events. If the code appeared shortly after a fill-up at an unfamiliar station, running the tank close to empty and refuelling with premium is a sensible first step.
