Why is the reductant pressure sensor so important?
Why is the reductant pressure sensor so important?
The reductant pressure sensor provides feedback to Powertrain Control Module ( PCM ), which regulates system pressure by controlling pump speed using pulse width modulation. The reductant pressure sensor is integral to reductant pump assembly. Need more information on how to fix the P204B code?
How much does a car pressure sensor cost?
Most auto repair shops charge between $75 and $150 per hour. How much do you know about cars? The reductant pressure sensor provides feedback to Powertrain Control Module ( PCM ), which regulates system pressure by controlling pump speed using pulse width modulation.
What does stored code p204b mean on pressure sensor?
A stored code P204B means that the powertrain control module (PCM) has detected a degree of voltage in the reductant pressure sensor circuit that’s not within the normal parameters. This code is exhibited in vehicles with a clean burning diesel engine, exclusively.
When to use code p2038 on air pressure sensor?
If the PCM detects a degree of voltage in the reductant injection air pressure sensor A circuit that is outside the normal range, a code P2038 will be stored and a malfunction indicator lamp (MIL) may be illuminated. Multiple ignition cycles – with a failure – may be required for MIL illumination.

Can a reductant pump screen be serviceable?
The reductant pump assembly houses the pump, reverting valve and solenoid, the pressure sensor, fine filter and DEF pump screen. The reductant pump assembly is only serviceable as a complete assembly. • The pump is Pulse-Width modulated by the PCM. Applying 12v to the pump will damage it.
Where does reductant go in a diesel engine?
Reductant (DEF)Injector • The reductant injector is a Pulse Width Modulated (PWM) solenoid controlled directly by the PCM. The injector receives reductant from the reductant pressure line and sprays it into the exhaust stream, where it is mixed into the exhaust gases before entering the catalyst.
