What Does Code P0351 Mean? DTC P0351 signifies a detected malfunction within the primary or secondary circuit of ignition coil “A”. In most engine configurations, “A” refers to the ignition coil responsible for cylinder #1. However, it is imperative to consult the vehicle-specific service manual to definitively identify which cylinder corresponds to “A,” particularly in […]

What Does Code P0352 Mean? DTC P0352 indicates a detected malfunction within the primary or secondary circuit of ignition coil ‘B’. The Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), assigns alphanumeric designations to ignition coils, where ‘B’ typically corresponds to cylinder #2 on inline engines or a specific cylinder on […]

What Does Code P0353 Mean? DTC P0353 signifies an detected malfunction within the primary or secondary circuit of the ignition coil designated for cylinder #3. The Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), is responsible for continuously monitoring the ignition system to ensure proper spark delivery. In a typical coil-on-plug […]

What Does Code P0354 Mean? Diagnostic Trouble Code (DTC) P0354 signifies an Ignition Coil D Primary/Secondary Circuit Malfunction. This code indicates that the Powertrain Control Module (PCM), or Engine Control Module (ECM), has detected an electrical fault within the primary or secondary circuit of the ignition coil responsible for cylinder ‘D’. The ‘D’ typically refers […]

What Does Code P0355 Mean? DTC P0355 signifies an detected malfunction within the primary or secondary circuit of ignition coil ‘E’. The Engine Control Module (ECM), also commonly referred to as the Powertrain Control Module (PCM), is responsible for monitoring the operational integrity of the ignition system for each individual cylinder. In a typical coil-on-plug […]

What Does Code P0356 Mean? Diagnostic Trouble Code (DTC) P0356 signifies an detected malfunction within the primary or secondary circuit of ignition coil ‘F’. In the vast majority of engine configurations adhering to SAE J1978 and J2012 standards, “Ignition Coil F” corresponds to the ignition coil responsible for cylinder #6. The Engine Control Module (ECM), […]

What Does Code P0357 Mean? DTC P0357 indicates an “Ignition Coil G Primary/Secondary Circuit Malfunction.” In the automotive diagnostic standard, the letter “G” is assigned by the vehicle manufacturer to a specific cylinder, typically referring to cylinder #7 in engines with eight or more cylinders (e.g., V8, V10). This code signifies that the Powertrain Control […]

What Does Code P0358 Mean? Diagnostic Trouble Code (DTC) P0358 indicates a detected malfunction within the primary or secondary circuit of ignition coil “H”. In a multi-cylinder engine, the “H” designation typically refers to the eighth ignition coil in the manufacturer’s specified cylinder numbering or firing order sequence. The Engine Control Module (ECM), also commonly […]

What Does Code P0359 Mean? Diagnostic Trouble Code (DTC) P0359 signifies an “Ignition Coil I Primary/Secondary Circuit Malfunction.” In most vehicle applications adhering to SAE J2012 standards, the ‘I’ in P0359 specifically refers to Ignition Coil #9. This indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an electrical fault […]

What Does Code P0360 Mean? The diagnostic trouble code P0360 signifies an “Ignition Coil J Primary/Secondary Circuit Malfunction”. This code indicates that the Powertrain Control Module (PCM), also referred to as the Engine Control Module (ECM), has detected an electrical fault within the primary or secondary circuit of ignition coil ‘J’. In the SAE J1930 […]
