TuningBot DTC Database · v4.37.14
8 manufacturer-specific interpretations across 7 manufacturers in the TuningBot DTC database.
ChryslerThe control module detected improper operation of the EGR Valve Pintle Position circuit. This is the manufacturer-specific definition used by Chrysler.
DodgeThe control module detected a fault associated with the Intermittent Loss Of Camshaft Position Or Crankshaft Position Sensor circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Dodge.
HondaThe control module detected a fault associated with the Exhaust gas recirculation (EGR) valve position sensor - circuit problem circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Honda.
HyundaiThe control module detected a fault associated with the Exhaust Gas Temperature not Plausible between Calculated and Simulated circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Hyundai.
MazdaThe control module detected a fault associated with the Differential pressure feedback sensor - downstream hose off or plugged 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.
Mechanical fault
ToyotaThe control module judged the Turbocharger (TC) pressure behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Toyota.
TC pressure sensor
VAGThe control module judged the EGR Temperature Sensor behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Audi.
The control module judged the EGR Temperature Sensor behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Volkswagen.

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.
