C3578 Dacia Logan Ii OBD Code

OBD/2 C3578 error code description and symptoms.

Mass Air Flow (MAF) Sensor Intermittent The MAF sensor circuit is monitored by the PCM for sudden voltage (or air flow) input change through the comprehensive component monitor (CCM). If during the last 40 warm-up cycles in key ON engine running the PCM detects a voltage (or air flow) change beyond the minimum or maximum calibrated limit, a continuous memory diagnostic trouble code (DTC) is stored.

Circuit High Input codes like C3578 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.

C3578 Dacia Logan Ii Error Code Repair Process :

When you turn on the ignition, the Service Engine Soon or Check Engine C3578 light should flash briefly, indicating that the OBD system is ready to scan your vehicle for any malfunctions. After this brief flash, the light should stay off while you drive as long as no problems are detected.

Common Causes of Dacia Logan Ii C3578 OBD2 Code

A common cause of code C3578 is the failure of Passenger Seat Occupant Detection Circuit Short To Ground, but there are several other possible causes as well, such as ;

Damaged camshaft position (CMP) sensor
Continuous oil flow to the VCT piston chamber
Fuel injector leaks
Starting system circuit Dead (Weak) battery

C3578 is a kind of Chassis Trouble Code

Diagnosing chassis noises can be one of the most frustrating problems technicians face. Fortunately, manufacturers have engineered noise, vibration and harshness (NVH) diagnostic techniques and equipment to find the source of the noise.
