P1194 is a trouble code indicating an incorrect or irrational performance has been detected for the Pulse Width Modulation (PWM). PWM is a technique used to control the power output of an engine. The most common cause of P1194 error code is usually caused by mechanical failures, such as worn-out spark plugs, faulty fuel injectors,…
P1195 O2 Sensor Slow During Catalyst Monitor is an error code that indicates the oxygen sensor signal to the PCM (Powertrain Control Module) takes too long to switch from rich to lean. This can be caused by a variety of issues, including faulty catalytic converters, low fuel pressure, carbon buildup on the exhaust system, faulty…
The P1198 Radiator Temperature Sensor Voltage Too High code indicates that the voltage of the radiator temperature sensor is too high. This could be due to a malfunctioning or faulty radiator temperature sensor, an electrical issue such as a wiring fault, or even low coolant levels in the cooling system. The radiator temperature sensor measures…
The “P1199 Radiator Temperature Sensor Voltage Too Low Code” is an OBD-II diagnostic trouble code that appears when the Engine Control Module (ECM) detects an unusually low voltage reading from the radiator temperature sensor. By continuously measuring the coolant temperature, the sensor assists the ECM in regulating the engine’s operating temperature within the optimal range….
When the P1243 Open or Shorted Condition Detected in the Turbocharger Surge Valve Solenoid Control is detected, it means that a fault has been detected within the solenoid control system. This fault can be caused by various things such as a faulty wiring harness, corroded connectors, an open circuit in the solenoid valve itself, or…
P1280 Open or Shorted Condition Detected in the Fuel System Relay Control Circuit is a diagnostic trouble code (DTC) that indicates an electrical malfunction within the fuel system relay control circuit. This circuit is responsible for controlling the fuel pump relay, which manages the fuel pump’s operation. The code suggests that there is an interruption…
The P1281 Engine Operating Temp Below the Acceptable Range code serves as an indicator that the engine’s operating temperature is currently below the acceptable range. This issue can arise due to various reasons, including a malfunctioning thermostat, coolant-related problems, a faulty coolant temperature sensor, or leaks in the cooling system. When this problem occurs, several…
P1282 is a diagnostic trouble code (DTC) that indicates an issue with the fuel pump relay control circuit. The P1282 code specifically draws attention to potential disruptions in the control circuit that regulates the fuel pump relay, a crucial component responsible for managing the fuel delivery process. Common causes of P1282 include faulty or loose…
P1283 Idle Select Signal Invalid is a diagnostic trouble code (DTC) that indicates an issue with the idle control system. This code typically means that there is either an issue with the idle air control valve, or the engine’s computer has detected an abnormal signal from its associated sensors. The P1283 code, it’s a red…
The P1284 Fuel Injection Pump Battery Voltage Out Of Range code is classified as a generic powertrain code. It is indicative of a problem within the fuel injection pump circuit, specifically related to battery voltage. The code is generated by the vehicle’s OBD-II system when the battery voltage falls outside the predetermined acceptable range for…
The P1285 Fuel Injection Pump Controller is a component of an automotive engine management system that monitors and controls the fuel injection pump. It is designed to be always on, meaning it should remain powered even when the engine is not running. This allows for quick start-up times when the ignition key is turned, as…
P1286 Accelerator Pedal Position Sensor Supply Voltage Too High is an error code that indicates a voltage issue in the accelerator pedal position sensor. This usually occurs when the supply voltage of the sensor exceeds its limits. The most common cause for this error code is a faulty or worn-out accelerator pedal position sensor, but…
