TuningBot DTC Database · v4.37.15
12 manufacturer-specific interpretations across 10 manufacturers in the TuningBot DTC database.
FordThe control module registered the fault condition described as "Idle Air Control Overspeed Error". This is the manufacturer-specific definition used by Ford.
HyundaiThe control module detected that the Idle Speed Control Actuator signal stayed above the expected range. This is the manufacturer-specific definition used by Hyundai.
JaguarThe control module detected that the Idle air control (IAC) valve - RPM value was lower than expected for the current conditions. This is the manufacturer-specific definition used by Jaguar.
KiaThe control module detected that the Idle air control (IAC) valve - opening coil signal stayed above the expected range. This is the manufacturer-specific definition used by Kia.
Land RoverThe control module detected a fault associated with the Idle air control (IAC) - value high circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Land Rover.
MazdaThe control module registered the fault condition described as "Idle air control (IAC) system - overspeed error". This is the manufacturer-specific definition used by Mazda.
MINIThe control module detected that the Idle Speed Control Valve Open Solenoid Control signal stayed above the expected range. This is the manufacturer-specific definition used by MINI.
MitsubishiThe control module detected that the Idle air control (IAC) valve - RPM value was lower than expected for the current conditions. This is the manufacturer-specific definition used by Mitsubishi.
PSAThe control module detected that the value received for the Air conditioning authorisation not received over the network was incorrect. 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.
The cited PSA workshop reference documents P1506 as "Intersystems CAN: Air-conditioning power-consumption value invalid or incoherent with the air-conditioning clutch status" for the Continental SID 807 injection ECU (DV6C 1.6 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
VAGThe control module detected a fault associated with the Closed throttle position (CTP) switch - does not open circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Audi.
The control module detected a fault associated with the Closed throttle position (CTP) switch - does not open circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Volkswagen.
Powertrain: engine, transmission and driveline systems.
Manufacturer-defined range: the meaning can differ between brands.
Specific fault index within the subsystem.
Diagnostic Trouble Code (12 interpretations). The control module registered the fault condition described as "Idle Air Control Overspeed Error". This is the manufacturer-specific definition used by Ford.
P1506 is a manufacturer-specific code. In this database it is documented for: Ford, Hyundai, Jaguar, Kia, Land Rover, Mazda, MINI, Mitsubishi, PSA, VAG. 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. 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.
