C1274 Possible Solution:
Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft. If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.
C1274 Code Meaning :
|OBD-II Diagnostic Chassis (C) Trouble Code For Engine||Fuel And Air Metering||Manifold Absolute Pressure/Barometric Pressure Circuit High Input||Cylinder 10 Contribution/balance Fault||Timing Reference High Resolution Signal A Too Many Pulses|
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate.
C1274 OBD-II Diagnostic Chassis (C) Trouble Code DescriptionC1274 engine trouble code is about Timing Reference High Resolution Signal A Too Many Pulses.
Main reason For C1274 CodeThe reason of C1274 OBD-II Engine Trouble Code is Manifold Absolute Pressure/Barometric Pressure Circuit High Input.
C1274 DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.
