TuningBot DTC Database · v4.37.15
19 manufacturer-specific interpretations across 12 manufacturers in the TuningBot DTC database.
BMWThe control module detected that the Knock sensor (KS) 2, bank 1 signal stayed above the expected range. This is the manufacturer-specific definition used by BMW.
ChryslerThe control module judged the TCM Internal Processor Clock behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Chrysler.
DodgeThe control module judged the TCM Internal Processor Clock behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Dodge.
JeepThe control module judged the TCM Internal Processor Clock behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Jeep.
LexusThe control module detected a communication fault involving Communication on the vehicle network. This is the manufacturer-specific definition used by Lexus.
MazdaThe control module detected a fault associated with the Generator voltage - no charge circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mazda.
OpelThe control module's internal test reported the Fuel injection pump control module as faulty. This is the manufacturer-specific definition used by Opel.
PSAThe control module detected the fault condition "ECU internal fault" for the Engine ECU. 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 stored code identifies a fault of the ECU internal fault. Documented for the Bosch MED 17.4.x engine ECU (EP6 THP family) on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
The stored code identifies a fault of the ECU internal fault. Documented for the Bosch MEV17.4 engine ECU (EP6 1.6 VTi) on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
The control module detected the fault condition "Internal fault (injection with no load)" for the ECU. Documented 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.
The control module detected the fault condition "internal fault(Injection with the foot lifted)" for the ECU. Documented for the Delphi DCM 3.5 injection ECU (DW10C 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The stored code identifies a fault of the Computer. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) on Peugeot applications; the same PSA control units are also fitted to Citroën models. PSA documentation does not characterise the failure mode further.
The control module detected the fault condition "internal fault" for the Engine ECU. Documented for the Siemens SID 803 injection ECU (DW10BTED4 2.0 HDi) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
SuzukiThe control module detected a fault associated with the Theft Deterrent Fuel Enable Signal Not Correct circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Suzuki.
ToyotaThe control module detected a communication fault involving Communication on the vehicle network. This is the manufacturer-specific definition used by Toyota.
VAGThe control module detected that the Accelerator pedal position (APP) sensor 1 signal stayed above the expected range. This is the manufacturer-specific definition used by Audi.
The control module detected that the Accelerator Position Sensor (G79) value was above the expected limit. This is the manufacturer-specific definition used by Volkswagen. Volkswagen Group tools also report it as fault code 18039. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
VolvoThe control module detected a communication fault involving CAN data bus, TCM on the vehicle network. 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 (19 interpretations). The control module detected that the Knock sensor (KS) 2, bank 1 signal stayed above the expected range. This is the manufacturer-specific definition used by BMW.
P1631 is a manufacturer-specific code. In this database it is documented for: BMW, Chrysler, Dodge, Jeep, Lexus, Mazda, Opel, PSA, Suzuki, Toyota, 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. 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.
