What is a generator field coil control circuit?
What is a generator field coil control circuit?
The field coil surrounds the generator armature and remains stationary in the alternator housing. The PCM monitors the continuity and voltage level of the generator field control circuit whenever the engine is running. The generator field coil is integral to generator operation and maintaining battery charge levels.
When to use a p0622 generator field control circuit malfunction?
If a problem is detected in monitoring the generator field control circuit, a code P0622 will be stored and a malfunction indicator lamp (MIL) may be illuminated,. Depending upon the perceived severity of the malfunction, multiple failure cycles may be necessary for MIL illumination. What is the severity of this DTC?
What is the OBD 2 fault code p0622?
OBD II fault code P0622 is a generic code that is defined as “Alternator, field control -circuit malfunction”, and is set when the PCM (Powertrain Control Module) detects an abnormal, or the absence of the PWM (Pulse Width Modulated) signal that turns the field winding in the generator on and off.
When to use trouble code for generator field?
Once the PCM enables the generator, the voltage regulator independently controls the generator. However, during this process, if it notices something is wrong with the generator field circuit, this trouble code is stored.
What does trouble code F on PCM mean?
All our repairs are backed by our 12-month / 12,000-mile warranty. This code is defined as the generator field “F” control circuit malfunctioning. When the PCM (powertrain control module) logs a P0622 trouble code, it’s because it’s detected a problem with the generator field control circuit.
What does p0622 mean on a Ford engine?
P0622 FORD Meaning The Engine Control Module (ECM) uses the generator turn on signal circuit to control the generator. A high side driver within the ECM allows the ECM to turn the generator ON and OFF. When Generator operation is desired, the ECM sends a 5 volt signal to the voltage regulator via the generator turn on signal circuit.
If a problem is detected in monitoring the generator field control circuit, a code P0622 will be stored and a malfunction indicator lamp (MIL) may be illuminated,. Depending upon the perceived severity of the malfunction, multiple failure cycles may be necessary for MIL illumination. What is the severity of this DTC?
Once the PCM enables the generator, the voltage regulator independently controls the generator. However, during this process, if it notices something is wrong with the generator field circuit, this trouble code is stored.
How much does it cost to diagnose a p0622 code?
The cost to diagnose the P0622 code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.
