TuningBot DTC Database · v4.37.14
8 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
ChevroletThe control module detected a fault associated with the Governor circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.
ChryslerThe control module detected a fault associated with the Governor 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.
MazdaThe control module detected improper operation of the Idle air control (IAC) system. This is the manufacturer-specific definition used by Mazda.
MINIThe control module detected that the Camshaft Position Actuator 'A' Control signal stayed above the expected range. This is the manufacturer-specific definition used by MINI.
PSAThe control module detected an internal control-unit fault (The charge signal from the alternator is higher than a maximum threshold). Documented for the Bosch EDC16C34 injection ECU (DV6TED4 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
VAGThe control module detected an interruption (open circuit) in the Camshaft position (CMP) actuator, Bank 1 circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Audi.
The control module detected an interruption (open circuit) in the Camshaft Timing Adj. Bank1 (N205) circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17936. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
Absence of Engine Torque in lower RPMs
VolvoThe control module detected that related sensor signals for Cruise control did not agree with each other (correlation/plausibility fault). This is the manufacturer-specific definition used by Volvo.
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (8 interpretations). The control module detected a fault associated with the Governor circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Chevrolet.
P1528 is a manufacturer-specific code. In this database it is documented for: Chevrolet, Chrysler, Mazda, MINI, PSA, VAG, Volvo. The same number can mean something different on other brands.
If the fault logic lives in the ECU calibration, yes: our DTC Removal file service disables the specific fault entry and, where the ECU needs it, corrects the checksum too. Not sure whether your case qualifies? Request a free assessment and our engineers will check your ECU file.
