TuningBot DTC Database · v4.37.15
10 manufacturer-specific interpretations across 8 manufacturers in the TuningBot DTC database.
BMWThe control module detected a fault associated with the O2 Sensor Circuit Slow Switching From Lean to Rich Bank 1 Sensor 1 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by BMW.
ChevroletThe control module detected a fault associated with the HO2S Heater Current Monitor Control Circuit Banks 1 and 2 Sensor 1 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 HO2S Heater Current Monitor Control Circuit Sensors 1 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.
DodgeThe control module judged the Ignition coil, 2 - secondary behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Dodge.
Mercedes-BenzThe control module detected improper operation of the Heated oxygen sensor (HO2S) 1. This is the manufacturer-specific definition used by Mercedes-Benz.
NissanThe control module detected that the Heated oxygen sensor (HO2S), bank 1, heater voltage stayed below the expected range. This is the manufacturer-specific definition used by Nissan.
PSAThe control module detected the fault condition "Mechanical blockage" for the Fault in the variable valve lift system. 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.
The control module detected the fault condition "Mechanical blockage" for the Fault in the variable valve lift system. 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.
VAGThe control module detected a fault associated with the Intake manifold air control valve position sensor - specification not attained 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 Intake Manifold Tuning Valve (N316): Setpoint Not Reached 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. Volkswagen Group tools also report it as fault code 17439. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).

Diagnostic Trouble Code (10 interpretations). The control module detected a fault associated with the O2 Sensor Circuit Slow Switching From Lean to Rich Bank 1 Sensor 1 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by BMW.
P1031 is a manufacturer-specific code. In this database it is documented for: BMW, Chevrolet, Chrysler, Dodge, Mercedes-Benz, Nissan, 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.
