What Does Code P0361 Mean? DTC P0361 signifies an detected malfunction within the primary or secondary circuit of ignition coil “K”. In modern ignition systems, the Engine Control Module (ECM), often referred to as the Powertrain Control Module (PCM), is responsible for precisely controlling the ignition coils to generate high-voltage sparks for combustion. Ignition coil […]

What Does Code P0362 Mean? DTC P0362 signifies an observed malfunction within the primary or secondary circuit of ignition coil “L”. The Engine Control Module (ECM), also commonly referred to as the Powertrain Control Module (PCM), is responsible for continuously monitoring the operational parameters of the vehicle’s ignition system. Specifically, the ECM monitors the voltage […]

What Does Code P0370 Mean? The diagnostic trouble code P0370 signifies a detected “Timing Reference High Resolution Signal A Malfunction” by the Engine Control Module (ECM) or Powertrain Control Module (PCM). This code specifically indicates an issue with the primary high-resolution timing reference signal, typically generated by the crankshaft position (CKP) sensor. The CKP sensor […]

What Does Code P0371 Mean? Diagnostic Trouble Code P0371 indicates a condition where the Engine Control Module (ECM), also commonly referred to as the Powertrain Control Module (PCM), has detected “Timing Reference High Resolution Signal A Too Many Pulses.” This code specifically refers to the high-resolution timing signal, which is typically provided by the Crankshaft […]

What Does Code P0372 Mean? The diagnostic trouble code P0372, “Timing Reference High Resolution Signal A Too Few Pulses,” indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an inconsistent or insufficient number of pulses from the primary high-resolution timing reference sensor, typically the Crankshaft Position (CKP) sensor. The ECM […]

What Does Code P0373 Mean? DTC P0373 signifies that the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), has detected an intermittent or erratic signal from the high-resolution timing reference sensor, typically the Crankshaft Position (CKP) sensor. The “Signal A” often refers to the primary CKP sensor signal output. The CKP […]

What Does Code P0374 Mean? The diagnostic trouble code P0374 signifies “Timing Reference High Resolution Signal A No Pulses.” This code indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) is not receiving the expected high-resolution timing reference signal from the designated “A” sensor. In most automotive applications, the “high resolution” timing […]

What Does Code P0375 Mean? The OBD-II diagnostic trouble code P0375, “Timing Reference High Resolution Signal B Malfunction,” indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an irregular, intermittent, or absent signal from a specific timing reference sensor. This “High Resolution Signal B” typically refers to a critical sensor […]

What Does Code P0376 Mean? DTC P0376 signifies that the Engine Control Module (ECM), often referred to as the Powertrain Control Module (PCM), has detected an excessive number of pulses from the Timing Reference High Resolution Signal B circuit. This “Timing Reference High Resolution Signal B” typically refers to a primary crankshaft position (CKP) sensor […]

What Does Code P0377 Mean? DTC P0377 indicates that the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), has detected an insufficient number of pulses from the “Timing Reference High Resolution Signal B.” In most automotive applications, “Signal B” refers to the crankshaft position sensor (CKP) signal, which provides high-resolution data […]
