P1340 Diagnostic Trouble Code (14 interpretations)
14 manufacturer-specific interpretations across 11 manufacturers in the TuningBot DTC database.
Ford
1 interpretation
Honda
1 interpretationThe control module detected a fault associated with the Ignition control module (ICM) - cylinder identification/synchronization 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.
Possible causes
- Wiring
- ignition coil(s)
- ICM
- ECM
Hyundai
1 interpretationThe control module detected a fault associated with the IFS 2 Open 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.
Jaguar
1 interpretationThe control module detected improper operation of the Camshaft Position Sensor B circuit. This is the manufacturer-specific definition used by Jaguar.
Mazda
1 interpretationThe control module detected improper operation of the Camshaft Position Sensor 'B' circuit. This is the manufacturer-specific definition used by Mazda.
Mercedes-Benz
1 interpretationThe control module detected a fault associated with the Camshaft position (CMP) sensor - signal 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.
Possible causes
- Wiring
- CMP sensor
- ECM
MINI
1 interpretationThe control module detected a fault associated with the Multiple Cylinder Misfire During Start circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by MINI.
Porsche
1 interpretationThe control module detected a fault associated with the Timing Chain out of Position Bank 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 Porsche.
PSA
3 interpretationsThe stored code identifies a fault of the Misfiring fault on cylinders 4. 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 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 stored code identifies a fault of the High combustion misfiring on cylinder 4. 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.
Toyota
1 interpretationThe control module detected improper operation of the Ignition control - cylinder No. 8 circuit. This is the manufacturer-specific definition used by Toyota.
Possible causes
- Wiring
- ignition module/coil
- ECM
VAG
2 interpretationsThe control module detected a fault associated with the Camshaft position (CMP) sensor 1/Bank 1/ crankshaft position (CKP) sensor - out of sequence 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.
Possible causes
- Valve timing
- CKP/CMP sensor installation
- CKP sensor rotor
The control module detected a fault associated with the Camshaft Position Sensor (G40) / Engine Speed Sensor (G28): Incor. Correlation 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 17748. Documented across Volkswagen Group applications (Audi, SEAT and Škoda included).
Possible causes
- Timing Belt/Chain incorrectly installed
- Camshaft Position Sensor (G40) faulty
- Engine Speed Sensor (G28) faulty
Recommended checks
- Check Timing Belt/Chain installation
- Check/Replace Camshaft Position Sensor (G40)
- Check/Replace Engine Speed Sensor (G28)
