17 manufacturer-specific interpretations across 15 manufacturers in the TuningBot DTC database.
The control module detected that the Mass air flow (MAF)/volume air flow (VAF), A - above value was above the expected limit. This is the manufacturer-specific definition used by BMW.
The control module detected a fault associated with the Loss Of RIM Serial Data 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.
The control module registered the fault condition described as "Engine control module (ECM) - internal fault". This is the manufacturer-specific definition used by Dodge.
ECM
The control module detected that the MIL request signal - circuit/ voltage stayed above the expected range. This is the manufacturer-specific definition used by Kia.
The control module detected improper operation of the Engine coolant thermostat circuit. This is the manufacturer-specific definition used by Land Rover.
The control module detected improper operation of the Secondary air injection driver (AIR), bank 2. This is the manufacturer-specific definition used by Lexus.
The control module detected a fault associated with the IFI Control Module N37 Voltage Or Fuel Metering Actuator Y231K1 Or Fuel Rack Position Sensor Y2311 circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Mercedes-Benz.
The control module did not receive the expected Immobilizer control module/module coding plug communication signal. This is the manufacturer-specific definition used by Nissan.
The control module detected that the Immobilizer control module state or value did not match what was expected. This is the manufacturer-specific definition used by Opel.
The control module detected a fault associated with the MIL Activated Externally circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Porsche.
The control module detected that the expected Accelerator pedal point of resistance information fault was absent. 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 control module detected that the Accelerator pedal hard point switch signal was not coherent with related operating data. Documented for the Magneti Marelli MM6KP engine ECU (EW7A/EW10A) on Peugeot applications; the same PSA control units are also fitted to Citroën models.
The control module detected that the expected Accelerator pedal point of resistance sensor information was absent. 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.
The control module registered the fault condition described as "Transponder response error". This is the manufacturer-specific definition used by Suzuki.
The control module detected improper operation of the Secondary air injection (AIR), bank 2. This is the manufacturer-specific definition used by Toyota.
The control module judged the MIL Call - Up Circuit Transmission Control Module behaviour implausible for the current operating conditions. This is the manufacturer-specific definition used by Volkswagen.
The control module detected improper operation of the Engine control module (ECM). This is the manufacturer-specific definition used by Volvo.

Diagnostic Trouble Code (17 interpretations). The control module detected that the Mass air flow (MAF)/volume air flow (VAF), A - above value was above the expected limit. This is the manufacturer-specific definition used by BMW.
P1614 is a manufacturer-specific code. In this database it is documented for: BMW, Chevrolet, Dodge, Kia, Land Rover, Lexus, Mercedes-Benz, Nissan, Opel, Porsche, 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.
