The NOx sensor on bank 1 — typically upstream of the SCR catalyst — does not communicate or sends an invalid s…
The bank 1 NOx sensor reports values outside the plausibility window against modeled NOx and the downstream se…
The NOx sensor signal on bank 1 is below the lower limit. Either short to ground on the analog return, sensor …
The NOx sensor signal on bank 1 is above the upper limit — short to supply, open ground, or a sensor that fail…
The bank 1 NOx sensor signal drops out intermittently. Typical cause is a marginal connector, harness chafing …
The heater inside the bank 1 NOx sensor cannot be controlled — open, short, or failed driver. Without proper h…
