P2420 Renault 12 OBD Code

OBD/2 P2420 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.

Some systems require that the actuator has an adequate supply of brake fluid. Low brake fluid levels can mimic the symptoms of code P2420, so consult the manual to locate the brake fluid reservoir. Bear in mind that a low fluid level can set code P2420 on some applications, so make sure that on fluid operated systems the fluid level is up to the mark before starting an electrical diagnosis.
