(1) If the resistance is more than 715 ohms (open circuit) (OAT more than 40 deg. C) or is less than 370 ohms (short circuit):
- do a check of the resistance of the spare sensor between pins A/E and A/F for correct value. (Ref. Fig. 202/TASK 30-42-00-991-007)
(a) If the resistance of the spare sensor is between 370 ohms and 715 ohms:
- connect pins B/U and B/V of the WHC1 (2DG1) to pins A/E and A/F of the spare sensor (Ref. AWM 30-42-03) and (Ref. ASM 30-42/01).
(b) If the resistance of the spare sensor is more than 715 ohms or less than 370 ohms:
