1) Key switch input voltage is 18V or more.
2) DTC P1630 or P1632 is not detected.

DTC Set Condition:
Barometric pressure sensor voltage is lower than 0.5 V.

Fault Judgement Period:
Approx. 5 sec.

Behavior When Trouble Occurs:
1) Due to back-up equivalent to 2500 m (8200 ft)
2) Black smoke emitted at high altitude
3) Output shortage at low altitude
4) Back-up: Barometric pressure default setting (80 kPa {11.6 psi}) EGR stopped

Diagnosis Lamp: ON

Recovery From Failure: *2

Possible Causes:
1) Barometric pressure sensor less than specified value.
2) Barometric pressure sensor more than specified value.
3) Open circuit or high resistance between ECM and barometric pressure sensor using breaker box or DDM.
4) Short circuit to barometric pressure sensor ground circuit.
5) Short circuit to ground between ECM and barometric pressure sensor using breaker box or DDM.
6) Bad barometric pressure sensor.
7) Barometric pressure display shows error value.
8) Looseness or disconnection to barometric pressure sensor.
