P052B Renault Alpine OBD Code

OBD/2 P052B 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 P052B 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.

If your variable intake solenoid #2 circuit malfunction check engine light is illuminated, it's best to take it in for diagnostic testing, which can feel like a hassle. Because while the lights vary in appearance from vehicle to vehicle, all have the same basic meaning: There's a problem with the car's emissions system. The on-board diagnostics system P052B and engine control unit are in charge of monitoring a bunch of different variable intake solenoid #2 circuit malfunction, and if they get a reading that's a little out of whack, up pops the check engine light.

Common Causes of Renault Alpine P052B OBD2 Code

A common cause of code P052B is the failure of Variable Intake Solenoid #2 Circuit Malfunction, but there are several other possible causes as well, such as ;

Damaged camshaft position (CMP) sensor
Faulty oil control valve (OCV)
Air fuel ratio (A/F) Sensor 1 Bank 1 circuit poor electrical connection
Damaged ECM

P052B 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.
