P3921 Porsche Panamericana OBD Code

OBD/2 P3921 error code description and symptoms.

The Camshaft Position sensor will signal the Engine Control Module when the #1 cylinder is ready for the spark plug to fire (top-dead-center on compression stroke). The ECM uses the information from this sensor to help calculate fuel delivery and spark timing.

Circuit High Input codes like P3921 are mostly caused by defective alternators that develop excessive voltages, although there may be other causes as well, such as short circuits that 'leak' current into a particular system from other, unrelated systems that work on higher voltages. Note that in the case of short circuits that leak power into a control circuit, there is likely to be other, seemingly unrelated trouble codes present along with the code(s) being investigated. Diagnosing a 'high input' code will always involve a thorough testing of the charging system as a first step, followed by measures to isolate the system from all other possible sources of power during resistance, continuity, and reference voltage tests.

P3921 Porsche Panamericana Error Code Repair Process :

If your vehicle failed a P3921 test and the P3921 Check Engine Light is NOT on, chances are you have a problem with the OBDII system, a burned out MIL lamp, or a faulty catalytic converter. The converter is essentially an afterburner that cleans up the exhaust after it exits the engine. The OBDII system uses park switch indicates park with vehicle moving a ownstream oxygen sensor to monitor the efficiency of the converter, and it should detect a drop in converter efficiency if the converter has been contaminated or is failing (ignition misfiring, leaky exhaust valves, and oil burning can all damage the converter). What you want to look park switch indicates park with vehicle moving: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression. Use your OBD Express DIY to look at the oxygen sensor outputs, coolant temperature, airflow, calculated engine load, and inlet air temperature.

Common Causes of Porsche Panamericana P3921 OBD2 Code

A common cause of code P3921 is the failure of Park Switch Indicates Park with Vehicle Moving, but there are several other possible causes as well, such as ;

• Clogged or faulty fuel injector (s)
• 1Camshaft Position Sensor circuit poor electrical connection
• Faulty Variable Camshaft Timing (VCT) position solenoid
• Incorrect Positive Crankcase Ventilation (PCV) hose connection

P3921 is a kind of Powertrain Trouble Code Powertrain of a modern automobile, comprising engine (with exhaust system), transmission, drive shaft, suspension and the wheels. In a motor vehicle, the term powertrain or powerplant describes the main components that generate power and deliver it to the road surface, water, or air.
