What Does Code P0195 Mean? DTC P0195 indicates a malfunction within the Engine Oil Temperature (EOT) sensor circuit. The Powertrain Control Module (PCM), often referred to as the Engine Control Module (ECM), relies on the EOT sensor to provide a voltage signal representing the engine oil’s current temperature. This critical data is used by the […]

What Does Code P0196 Mean? DTC P0196 signifies that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an anomalous signal from the Engine Oil Temperature (EOT) sensor. This code indicates that the sensor’s input voltage or resistance value falls outside of the expected operational range or exhibits performance characteristics inconsistent with […]

What Does Code P0197 Mean? DTC P0197 signifies that the Engine Control Module (ECM), also commonly referred to as the Powertrain Control Module (PCM), has detected an electrical signal from the Engine Oil Temperature (EOT) sensor that is below its expected operational range. This typically translates to a voltage signal that is lower than the […]

What Does Code P0198 Mean? The diagnostic trouble code P0198 signifies a fault within the Engine Oil Temperature (EOT) Sensor ‘A’ Circuit, specifically indicating a “Circuit High” condition. This means the Engine Control Module (ECM) or Powertrain Control Module (PCM) is detecting a voltage signal from the EOT sensor that is excessively high, exceeding the […]

What Does Code P0199 Mean? DTC P0199 indicates an intermittent fault within the Engine Oil Temperature (EOT) sensor circuit. The Powertrain Control Module (PCM), also referred to as the Engine Control Module (ECM) on some platforms, continuously monitors the voltage signal from the EOT sensor. This sensor is typically a Negative Temperature Coefficient (NTC) thermistor, […]

What Does Code P0200 Mean? DTC P0200, “Injector Circuit Malfunction,” indicates that the Engine Control Module (ECM), also commonly referred to as the Powertrain Control Module (PCM), has detected an electrical fault within the general fuel injector control circuit. Unlike specific injector codes such as P0201 (Cylinder 1 Injector Circuit Malfunction) through P0208, P0200 signifies […]

What Does Code P0201 Mean? The diagnostic trouble code P0201 signifies an electrical malfunction within the primary control circuit of the fuel injector for Cylinder 1. The Engine Control Module (ECM) or Powertrain Control Module (PCM) continuously monitors the electrical integrity and operational characteristics of each fuel injector circuit. During active operation, the ECM commands […]

What Does Code P0202 Mean? Diagnostic Trouble Code (DTC) P0202 signifies an electrical malfunction within the fuel injector control circuit for engine cylinder number two. The Engine Control Module (ECM), often referred to as the Powertrain Control Module (PCM), is responsible for precisely timing the activation and deactivation of each fuel injector. When the ECM […]

What Does Code P0203 Mean? The diagnostic trouble code P0203 indicates that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an electrical malfunction in the control circuit for the fuel injector supplying cylinder #3. The ECM/PCM continuously monitors the electrical integrity and operational characteristics of each fuel injector circuit. When the […]

What Does Code P0204 Mean? DTC P0204 indicates an “Injector Circuit Malfunction” specifically for Cylinder 4. This signifies that the Engine Control Module (ECM) or Powertrain Control Module (PCM) has detected an electrical anomaly within the control circuit of the fuel injector dedicated to the fourth cylinder. The ECM continuously monitors the electrical characteristics of […]
