P242D

Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 3

P242D is a generic OBD-II powertrain diagnostic trouble code: Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 3. It is logged by the engine control unit when the powertrain monitor detects that a specific fault threshold has been exceeded — typically resulting in the malfunction-indicator lamp (MIL / check-engine light) being illuminated.

Disabling P242D in software

RaceTune can permanently disable P242D — and any other OBD-II diagnostic trouble code — on every ECU family we support. The monitor is disabled inside the ECU itself, so the fault stops being logged: the warning light stays off and the engine never enters limp mode for this code. The change is tied to your exact software version.

Permanent
The monitor is disabled in the ECU itself — not just cleared. It cannot return.
Tailored to your file
Each patch is matched to your specific software version — never a one-size-fits-all file.
Reversible
The original file is always preserved. Reflash the stock to return the ECU to factory state.
