What does p20bd mean on a reductant heater?
A stored code P20BD means that the powertrain control module (PCM) has detected no voltage in the control circuit for the on-board reductant heater designated with the letter B. This designation is used where multiple reductant heaters are in use, consult a vehicle specific repair manual to determine which is the B circuit for your application.
What is the reductant heater control system used for?
The reductant heater control system is used by the Powertrain Control Module (PCM) to heat up the Diesel Exhaust Fluid (DEF) to prevent it from freezing.
Where are the reductant heaters located in a diesel engine?
Reductant heaters are used to prevent diesel exhaust fluid from freezing during extreme temperatures. These heaters are typically located in the DEF reservoir and/or the reductant injector supply hose/s.
What does p20bd stand for in Powertrain Control Module?
Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration. A stored code P20BD means that the powertrain control module (PCM) has detected no voltage in the control circuit for the on-board reductant heater designated with the letter B.
Where is the p20bd code located on a reductant heater?
These heaters are typically located in the DEF reservoir and/or the reductant injector supply hose/s. If the PCM detects no voltage on the control circuit for reductant heater B, a code P20BD will be stored and a malfunction indicator lamp may be illuminated.
Where are reductant heaters located in the Def reservoir?
Reductant heaters are used to prevent diesel exhaust fluid from freezing during extreme temperatures. These heaters are typically located in the DEF reservoir and/or the reductant injector supply hose/s. If the PCM detects no voltage on the control circuit for reductant heater B, a code P20BD will be stored…

What is the code for a Duramax reductant tank heater?
By using a code reader the most common code is P20B9, DEF reservoir heater control open circuit/low voltage. The most common repair for the P20B9 code is either replacing or manually engaging the reductant tank heater.
What are the symptoms of a p20bd trouble code?
Symptoms of a P20BD 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 diagnose p20bd Ford heater control circuit?
Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. The cost to diagnose the P20BD FORD 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.

Is the DTC p20bd the same as the p20be?
Warren, both DTC’s P20BD and P20BE are specific to the reductant line heater. Yes, the line going from the DEF tank to the injector on the exhaust filter is indeed heated. Since you are not reporting any glow plug system or tank heater DTC’s we can hone right in on the line heater.
What are the p20bd and p20be codes on my F250?
I’m here today because my 2015 F250 just started exhibiting these codes (P20BD and P20BE). It got lightly T-boned in an intersection about two months ago and just came back from the body shop last Friday. It started with the CEL and these codes on Monday, but otherwise seems fine.
What is code p20b9 Def supply line heater?
With the scan tool hooked up, see if code P20B9 DEF Supply Line Heater Circuit High Input is now active after 15 seconds. If this happens, then the wiring, DEF control unit/module and PCM are good. The most likely problem is the DEF Supply Line Heater.
What are the problems with OBD code p20bd?
Easy Diagnosis Of Engine Error OBD Code P20BD 1 Non performance of the glow plug control module 2 Failure in the car wiring 3 The reductant tank heater might not function properly
What causes an open circuit on a reductant heater?
Causes for this code may include: Bad reductant heater. Open or shorted circuits in the reductant heater control. Defective reductant temperature sensor.
Where is the glow plug number on a sprinter?
Check the error code, it will be a number between P0671 and P0676, where the last digit indicates the glow plug number (i.e. P0675 is for glow plug in cylinder #5). I have read that engine codes for the older T1N (2002-2006) Sprinter are unreliable, but this isn’t a problem for the NCV3.
