C0765 Mazda B4000 OBD Code

OBD/2 C0765 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 C0765, so consult the manual to locate the brake fluid reservoir.

What you want to look anti theft horn output circuit short to batt: Any conditions that might cause ignition misfire, an overly rich or lean fuel condition, or loss of compression.
