A local parts store scanned the ECM and recorded diagnostic-trouble code P2206, which is associated with a bad NOx sensor. The code was cleared, and I will replace the sensors.

The Virtual NOx sensor is validated on a state-of-the-art EURO-VI Heavy Duty Diesel Engine. Steady-state validation results show that the performance of the Virtual NOx sensor is similar to the ...

GM has issued a service update for certain 2021 Chevy Silverado HD and GMC Sierra HD pickups that may have been delivered with a damaged diesel NOx sensor.

Limp mode is something you don't want your Cummins engine to go into. However, if it does happen, here's why and what you ...

The knock sensor alerts the engine-management computer that knock is occurring, and the computer then retards the ignition timing to correct for it.

They all have knock sensors that automatically adjust the timing if you happen to get gasoline that has too low of an octane rating. So it's possible you have a bad knock sensor.

“P0324” is the code for a knock sensor malfunction. Bad gas (with too low an octane rating) could cause knocking, which might turn on the “check engine” light.

Knock in diesel/natural gas dual fuel engines is a well known yet not fully understood complex phenomenon that requires consideration in any attempt to increase load and efficiency. Thus combustion ...
