The turbocharger position sensor signal is below the lower limit — short to ground or sensor at zero stop.…
The turbocharger position sensor signal is above the upper limit — short to supply, open ground or sensor fail…
Direct Ozone Reduction (DOR) catalysts are coated radiator surfaces or dedicated catalysts that decompose trop…
The idle-speed selector input is open. On commercial vehicles this switch lets the operator pick a fast-idle s…
The idle-speed selector input is electrically intact but the value does not match a valid preset — multiple po…
Idle-speed selector input reads stuck low — short to ground or analog signal at minimum. Wiring faults of this…
Idle-speed selector input reads stuck high — short to battery voltage or analog signal at maximum. Wiring faul…
The idle-speed selector signal jumps or drops out — usually a worn rotary contact or vibration. Wiring faults …
A/C request input B is electrically intact but its value does not match the system context — same failure mode…
The DOR catalyst temperature sensor reads stuck high — short to reference voltage or open signal return. Witho…
The DOR catalyst temperature sensor signal jumps or drops out — typically loose connectors or chafed wiring ne…
General electrical fault on the DOR catalyst deterioration sensor circuit. This sensor estimates the remaining…
The DOR deterioration sensor is electrically intact but its readings drift or do not match the model — for exa…
The DOR deterioration sensor signal voltage reads below the lower limit — short to ground or internal short.…
The DOR deterioration sensor signal voltage reads above the upper limit — short to reference voltage or open s…
The DOR deterioration sensor signal jumps or drops out — typically loose connectors or chafed wiring near the …
The DOR catalyst no longer reduces tropospheric ozone with the required efficiency, based on the deterioration…
General electrical fault on the turbocharger/supercharger shaft speed sensor A — a high-frequency Hall or eddy…
Turbo speed sensor A is electrically intact, but the speed reading does not match the model — for example a sp…
The control circuit that drives the vacuum reservoir control valve (or vacuum pump motor) is open. The ECM can…
The vacuum reservoir control circuit reads stuck low — short to ground or low-side driver stuck on. The actuat…
The vacuum reservoir control circuit reads stuck high — short to battery voltage or open coil. The driver cann…
The hood switch is electrically intact, but its state is implausible — for example reporting hood-open while v…
The hood switch input reads stuck low — short to ground or stuck-closed switch. The body controller may treat …
