OBDII Code P2262 – Turbo/Supercharger Boost System Fault
Meaning of Code P2262
Code P2262 indicates a problem detected by the Engine Control Module (ECM) in the turbocharger boost system. It is often related to a malfunction of the Variable Geometry Turbocharger (VGT), which is electronically controlled by a Turbo Actuator.
The Electronic Turbo Actuator receives information via the CAN BUS from the ECM module and performs its own diagnostics. If an anomaly is detected, it sends an error message to the ECM, which interprets it and generates the P2262 code.
The ECM illuminates the Malfunction Indicator Lamp (MIL) if the problem persists for two consecutive driving cycles. It will turn off after four cycles without detecting the problem.
Possible Symptoms
- Illuminated Malfunction Indicator Lamp (or “Service Engine Soon” warning light).
Possible Causes
- ECM module calibration update required.
- Soot buildup on the turbocharger.
- Faulty turbocharger.
How to Fix Code P2262?
- Check the possible causes listed above.
- Visually inspect the wiring harness and associated connectors.
- Look for damaged components.
- Check for broken, bent, pushed out, or corroded connector pins.
- Clean or replace the turbocharger if it is clogged or faulty.
- Check if an ECM software update is available.
If in doubt, it is recommended to consult a turbocharger specialist mechanic.
