B3789 Citroen 15 OBD Code

OBD/2 B3789 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 B3789 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.

Common Causes of Citroen 15 B3789 OBD2 Code

A common cause of code B3789 is the failure of Air Temperature Internal Sensor Circuit Short To Ground, but there are several other possible causes as well, such as ;

Damaged camshaft position (CMP) sensor
Exhaust gas leaks
Clogged or faulty fuel injector (s)
Oil flow restriction in the oil passages or the VCT valve body
