What Does Code P1211 Mean? DTC P1211 signifies that the Engine Control Module (ECM), also known as the Powertrain Control Module (PCM), has detected an inconsistency between the actual Injector Control Pressure (ICP) and the desired ICP value within the high-pressure oil system. This code is predominantly found in diesel engines, particularly Ford Power Stroke […]

What Does Code P1212 Mean? DTC P1212 signifies that the Engine Control Module (ECM), also commonly referred to as the Powertrain Control Module (PCM), has detected insufficient Injector Control Pressure (ICP) during the engine cranking cycle. This code is predominantly associated with diesel engines, particularly those utilizing a Hydraulically Actuated, Electronically Controlled, Unit Injector (HEUI) […]

What Does Code P1213 Mean? The OBD-II diagnostic trouble code P1213 signifies a detected malfunction within the Start Injector Circuit. This code is typically associated with vehicles equipped with a dedicated cold start injector (CSI), which is an auxiliary fuel injector separate from the primary fuel injectors. The CSI’s function is to provide an enriched […]

What Does Code P1214 Mean? DTC P1214 signifies “Pedal Position Sensor B Circuit Intermittent.” This code indicates that the Powertrain Control Module (PCM), also referred to as the Engine Control Module (ECM), has detected an inconsistent or sporadic electrical signal from Accelerator Pedal Position (APP) Sensor Circuit B. Modern vehicles utilize an Electronic Throttle Control […]

What Does Code P1215 Mean? The diagnostic trouble code P1215 signifies a Pedal Position Sensor C Circuit Low Input. In modern vehicles equipped with Electronic Throttle Control (ETC), often referred to as “drive-by-wire” systems, the Accelerator Pedal Position (APP) sensor is a critical input to the Powertrain Control Module (PCM) or Engine Control Module (ECM). […]

What Does Code P1216 Mean? The OBD-II diagnostic trouble code P1216 signifies an issue with the Accelerator Pedal Position (APP) Sensor ‘C’ Circuit High Input. The APP sensor, often referred to as the Pedal Position Sensor (PPS), is a critical component of the Electronic Throttle Control (ETC) system, commonly known as “drive-by-wire.” Its primary function […]

What Does Code P1217 Mean? DTC P1217 signifies an detected intermittent fault within the “C” circuit of the Accelerator Pedal Position (APP) sensor. In modern drive-by-wire (DBW) systems, the APP sensor is a critical input device that translates the driver’s throttle demand into an electrical signal for the Powertrain Control Module (PCM) or Engine Control […]

What Does Code P1218 Mean? The diagnostic trouble code P1218, often defined as “Cylinder Identification (CID) Input High,” indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an abnormally high voltage signal from the Cylinder Identification circuit. The Cylinder Identification signal is primarily provided by the Camshaft Position (CMP) sensor, […]

What Does Code P1219 Mean? The OBD-II diagnostic trouble code P1219 signifies “Cylinder Identification (CID) Low”. This code is detected by the Engine Control Module (ECM) or Powertrain Control Module (PCM) when it receives a voltage signal from the Camshaft Position (CMP) sensor that is consistently below its expected operating range, intermittently dropping to an […]

What Does Code P1220 Mean? DTC P1220 signifies a detected malfunction within the Series Throttle Control System. This code is typically set in vehicles equipped with an Electronic Throttle Control (ETC) system, also known as “drive-by-wire.” In such systems, the Engine Control Module (ECM), or Powertrain Control Module (PCM), directly manages the throttle plate position […]
