P · PowertrainEngineOBD2

Chrysler

1 interpretation
P1290
Compressed natural gas pressure sensorpressure high Chrysler · engine Data confidence 62%

The control module detected a fault associated with the Compressed natural gas pressure sensorpressure high 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.

Possible causes

  • Compressed natural gas system
  • wiring
  • compressed natural gas pressure sensor

Ford

1 interpretation
P1290
Cylinder Head Temperature Sensor Signal Less Than Self - Test Range Ford · engine Data confidence 80%

The control module detected a fault associated with the Cylinder Head Temperature Sensor Signal Less Than 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
  • cooling system fault
  • CHT sensor

Recommended checks

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

Honda

1 interpretation
P1290
Throttle position (TP) motor - forced idle mode Honda · engine Data confidence 62%

The control module detected a fault associated with the Throttle position (TP) motor - forced idle mode 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
  • APP sensor
  • TP motor
  • mechanical fault
  • ECM

Hyundai

1 interpretation
P1290
Pressure Limit Valve (DVB3) Error Hyundai · engine Data confidence 62%

The control module registered the fault condition described as "Pressure Limit Valve (DVB3) Error". This is the manufacturer-specific definition used by Hyundai.

Jeep

1 interpretation
P1290
CNG Fuel Pressure Too High Jeep · fuel Data confidence 62%

The control module detected that the CNG Fuel Pressure value was above the expected limit. This is the manufacturer-specific definition used by Jeep.

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
