What does p20be mean on a reductant heater?
Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration. A stored code P20BE means that the powertrain control module (PCM) has detected improper voltage that is outside the normal expected value range within the control circuit for the on-board reductant heater designated with the letter B.
What is trouble code for reductant heater B?
The trouble code P20BD can be defined as Reductant Heater B Control Circuit/Open. Is the car engine not performing as per the expectations? Are you noticing affected fuel economy, increased emissions from the tailpipe and check engine light illuminated on the dashboard?
What does the p20ba code on a heater mean?
P20BA code means that your vehicle’s PCM has detected that the voltage signal from the control circuit of the designated reductant heater “A” is out of the expected range. Note: The definition of code P20BA may be different depending on the vehicle manufacturer. Consult the appropriate repair manual or repair database for the exact code definition
What are the symptoms of a p20be trouble code?
Symptoms of a P20BE trouble code may include: Diminished engine performance Excessive black smoke from vehicle exhaust Reduction in fuel efficiency What are some of the common causes of the code? Causes for this code may include: Open or shorted circuits in the reductant heater control Defective reductant temperature sensor

How to test the reductant heater control circuit?
If the appropriate power (battery voltage) and ground circuits are discovered, use the scanner to activate the reductant heater/s and test output control circuit voltage. If voltage is insufficient, suspect that the controller is bad or has experienced a programming error.
