Frequently asked questions about P1527
What does P1527 mean?
Diagnostic Trouble Code (7 interpretations). The control module detected a fault associated with the Transmission Range Pressure Switch Comparison circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chrysler.
Is P1527 generic or manufacturer-specific?
P1527 is a manufacturer-specific code. In this database it is documented for: Chrysler, Hyundai, Mazda, MINI, PSA, VAG. The same number can mean something different on other brands.
Can TuningBot remove P1527 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.
