Gaz 28 P262E Engine Trouble Code
What is Gaz 28 P262E?
Gaz 28 P262E 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.
P262E on the Gaz 28
Owners of the Gaz 28 should be aware that P262E can appear alongside oil consumption warnings. Low oil pressure caused by a worn PCV system lets crankcase vapour contaminate the mass air flow sensor, sending erroneous readings to the ECU.

How to Fix Gaz 28 P262E
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:
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:
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 28 P262E Repair Cost
PCV system overhaul on the Gaz 28 — which resolves oil-mist contamination of the MAF sensor — costs $100–$200. The MAF sensor should be cleaned ($15–$25 DIY) or replaced ($80–$150) at the same time to ensure accurate fuelling after the fix.
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 28
On Gaz 28 vehicles, the turbo boost solenoid and the MAP sensor feed into the same diagnostic path. P262E caused by a faulty boost solenoid is sometimes charged to the customer as a MAP sensor replacement, doubling unnecessary parts spend.
DIY Repair Guide: P262E on Gaz 28
Clearing P262E on your Gaz 28 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 P262E on the Gaz 28
Using only genuine or OEM-specification fuel injectors in the Gaz 28 ensures precise spray pattern and flow rate. Inferior aftermarket injectors are a documented trigger for P262E through off-target fuel delivery.
