BMW

1 interpretation
P1408
Electronic stability program (ESP) control switch - input too high BMW · engine Data confidence 62%

The control module detected that the Electronic stability program (ESP) control switch - input value was above the expected limit. This is the manufacturer-specific definition used by BMW.

Possible causes

  • Wiring shorted to positive
  • wiring open circuit
  • connections
  • ESP control switch

Chrysler

1 interpretation
P1408
Intake Manifold Pressure Sensor Circuit Chrysler · engine Data confidence 62%

The control module detected improper operation of the Intake Manifold Pressure circuit. This is the manufacturer-specific definition used by Chrysler.

Recommended checks

  • Perform a full module scan
  • Review freeze-frame and occurrence data
  • Confirm the exact vehicle, ECU and software context
  • Inspect relevant wiring and connectors
  • Check applicable OEM service information

Ford

1 interpretation
P1408
EGR Flow Out Of Self - Test Range Ford · emissions Data confidence 80%

The control module detected a fault associated with the EGR Flow Out Of Self - Test Range circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Ford.

Possible causes

  • Wiring
  • EGR hoses
  • EGR valve
  • EGR solenoid
  • ECM

Recommended checks

  • Perform a full module scan
  • Review freeze-frame and occurrence data
  • Compare commanded and measured values
  • Check applicable OEM service information

Jaguar

1 interpretation
P1408
Exhaust gas recirculation (EGR) solenoid Jaguar · emissions Data confidence 80%

The control module detected a fault associated with the Exhaust gas recirculation (EGR) solenoid circuit or function; the stored code identifies the affected component rather than a single failure mode. This is the manufacturer-specific definition used by Jaguar.

Possible causes

  • Wiring
  • EGR solenoid
  • EGR temperature sensor

Land Rover

1 interpretation
P1408
Exhaust gas recirculation (EGR) system - incorrect flow detected Land Rover · emissions Data confidence 62%

The control module detected that the Exhaust gas recirculation (EGR) system state or value did not match what was expected. This is the manufacturer-specific definition used by Land Rover.

Possible causes

  • Hose leak/blockage
  • wiring
  • EGR valve
  • EGR solenoid
  • ECM

Mazda

1 interpretation
P1408
Exhaust gas recirculation (EGR) system - flow out of self - test range Mazda · emissions Data confidence 80%

The control module detected a fault associated with the Exhaust gas recirculation (EGR) system - flow out of self - test range 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.

Possible causes

  • Wiring
  • EGR solenoid valve
  • mechanical fault

VAG

1 interpretation
P1408
Exhaust gas recirculation temperature (EGRT) sensor - high input VAG · emissions Data confidence 62%

The control module detected that the Exhaust gas recirculation temperature (EGRT) signal stayed above the expected range. This is the manufacturer-specific definition used by Audi.

Possible causes

  • Wiring short to positive
  • ground wire defec tive
  • EGRT sensor
Applies to Audi

Volvo

1 interpretation
P1408
Outside air temperature sensor - no signal Volvo · engine Data confidence 62%

The control module did not receive the expected Outside air temperature signal. This is the manufacturer-specific definition used by Volvo.

Possible causes

  • Wiring
  • poor connection
  • outside air temperature sensor
  • ECM
