Frequently asked questions about P1351
What does P1351 mean?
Diagnostic Trouble Code (14 interpretations). The control module detected that the signal in the IC Circuit High Voltage circuit stayed above the expected operating range. This is the manufacturer-specific definition used by Chrysler.
Is P1351 generic or manufacturer-specific?
P1351 is a manufacturer-specific code. In this database it is documented for: Chrysler, Dodge, Ford, Hyundai, Land Rover, Mercedes-Benz, MINI, PSA, Toyota, VAG, Volvo. The same number can mean something different on other brands.
Can TuningBot remove P1351 at file level?
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry. Checksum correction is not included: it is a separate, optional service. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
