P0641 code is logged whenever the PCM detects voltage that does not match manufacturer specifications on the 5-volt reference circuit.
How do I fix code P0641?
Easy Diagnosis Of Engine Error OBD Code P0641
Check system fuses and fusible links with the circuit under a full load and blown fuses should be replaced. Perform a visual inspection of sensor system related wiring harnesses and connectors.
What does P0641 mean?
Code P0641 indicates the PCM has detected voltage is out of specification on the 5-Volt reference circuit. The ‘A’ part of the code indicates the problem is with the number one sensor, if more than one sensor is in question.
What causes a P0641 code?
P0641 code is logged whenever the PCM detects voltage that does not match manufacturer specifications on the 5-volt reference circuit. Rail 1 feeds the Engine Oil Pressure Sensor, the Fuel Rail Pressure Sensor, the A/C refrigerant pressure sensor, the Exhaust Pressure Differential sensor, the Camshaft Position Sensor.
What causes code P1682?
OBD II fault code P1682 is a manufacturer-specific trouble code that is defined by carmaker General Motors as “Driver 5 Line 2” and is set when the PCM (Powertrain Control Module) detects a difference in voltage that exceeds a maximum allowable threshold between two circuits that supplies it with battery voltage.
What is reference voltage in car?
A reference voltage is sent to the sensor from the on-board computer. The sensor’s resistance decreases as the engine increases. The temperature of the vehicle can be determined by the computer. When the engine is at operating temperature.
