TuningBot DTC Database · v4.37.15
11 manufacturer-specific interpretations across 10 manufacturers in the TuningBot DTC database.
DodgeThe control module detected that the Ambient/Battery Temperature Sensor Volts value was below the expected limit. This is the manufacturer-specific definition used by Dodge.
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 improper operation of the Idle air control (IAC) valve circuit. This is the manufacturer-specific definition used by Jaguar.
KiaThe control module detected that the Idle air control (IAC) valve - closing coil signal stayed above the expected range. This is the manufacturer-specific definition used by Kia.
Land RoverThe control module detected improper operation of the Idle air control (IAC) valve circuit. This is the manufacturer-specific definition used by Land Rover.
LexusThe control module detected a fault associated with the PTC AC Auxiliary Heater Disabled 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 Lexus.
MazdaThe control module detected an interruption (open circuit) in the Idle air control (IAC) valve 1 - short/ circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by Mazda.
MINIThe control module detected an interruption (open circuit) in the Idle Speed Control Valve Opening Solenoid Control circuit, so the expected electrical continuity was not present. This is the manufacturer-specific definition used by MINI.
OpelThe control module detected improper operation of the Idle air control (IAC) valve circuit. This is the manufacturer-specific definition used by Opel.
VAGThe control module detected that the Idle speed control (ISC) value was above the expected limit. This is the manufacturer-specific definition used by Audi.
The control module detected that the monitored Idle Control Sys: Upper Regulation value reached its permissible limit. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 17916. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).

Diagnostic Trouble Code (11 interpretations). The control module detected that the Ambient/Battery Temperature Sensor Volts value was below the expected limit. This is the manufacturer-specific definition used by Dodge.
P1508 is a manufacturer-specific code. In this database it is documented for: Dodge, Hyundai, Jaguar, Kia, Land Rover, Lexus, Mazda, MINI, Opel, 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.
