P203B Reductant Level Sensor - Web google tell me it is probably reductant level sensor circuit range/performance. The engine control module (ecm) monitors the reductant level sensor. Time for the job is stated as 0.4 hours and not covered under any extended warranty. Web an integrated temperature sensor monitors reductant temperature. This code is often seen in diesel engines, which use a reductant (diesel exhaust fluid or def) to reduce harmful emissions. Here are the steps you can take to fix the p203b code: Web frozen reductant cannot be detected. If the pcm detects an implausible signal from the reductant level sensor, code p203b is set. Web if you see the engine light on or the service engine soon warning light, it could be due to the p203b fault code. Check def quality and level:

Ensure correct def is used and levels are appropriate. This may be due to a low voltage condition during engine cranking. If the pcm detects an implausible signal from the reductant level sensor, code p203b is set. It could be as simple as a low supply, or it could be a bad sensor or something. Assess the reductant level sensor and its wiring for damage or corrosion.

Attached some documentation if you haven't already looked through it, page 8 is the brief section on p205c. Ensure correct def is used and levels are appropriate. If the pcm detects an implausible signal from the reductant level sensor, code p203b is set. This dtc sets if the pcm detects an irrational reading, such as rdl1 (top pin) indicating a full tank while rdl3 (bottom pin) is indicating an empty tank.

Web the dtc does seem to be specifically related to the tank. To my knowledge my def tank is full (if i. Reductant level sensor circuit range/performance.

It could be as simple as a low supply, or it could be a bad sensor or something. Web i know this post was from a long long time ago but my 2016 2500hd (80k miles) just threw p203b and after reading this thread i went searching for an updated bulletin that included later model years. Web the p203b code is a generic powertrain code indicating a reductant level sensor circuit problem.

Verify If The Engine Control Module Is Operating Correctly.

Web google tell me it is probably reductant level sensor circuit range/performance. This dtc sets if the pcm detects an irrational reading, such as rdl1 (top pin) indicating a full tank while rdl3 (bottom pin) is indicating an empty tank. This sensor is usually built into the reductant tank. Learn what reductant level sensor circuit range/performance means, location and how to repair?

What Is Your Def Level?

The engine control module (ecm) monitors the reductant level sensor. It could be as simple as a low supply, or it could be a bad sensor or something. This code is usually caused by a faulty reductant level sensor, an open or shorted reductant level sensor harness, or a poor electrical connection in. To my knowledge my def tank is full (if i.

P203B Is The Trouble Code Defined As Reductant Level Sensor Circuit Range/Performance And Indicates A Detected Unexpected Electrical Reading From The Sensor Circuit As Identified By The Ecm.

It sounds like the first thing to do is to check the level of your def (diesel exhaust fkuid) or adblue. The measured level will be used to update the calculation of remaining quantity in the reductant tank.
