ERROR E1921
Hi!

We recently change the DPF filter to our forklift Hyster H16XMS-12 because this part was damage and need to be replace, but after the change, the instrument display show the Error E1921.

I search in the "Cummins Engine Fault Code Guide" and found the error: Aftertreatment Particulate Filter Differential Pressure - Data Valid But Above Normal Operating Range - Moderately Severe Level

What do you recommend us to do to fix this error? I appreciate any help you can give us.

"Unicarriers - it would have to be for a dual fuel unit also. Usually a bad cam or crankshaft sensor will throw a E-27 or a E-28 code on the dash panel... If it does not light up and the bulb is bad then it will not start also."

Fact of the week
Sourdough bread contains Lactobacillus reuteri, a probiotic bacteria. During pregnancy and breastfeeding, these bacteria can travel from the mother's colon to her breast tissue and be passed to the infant through breast milk. It offers various health benefits, including potential protection against breast cancer.
