DTC detecting condition

Possible cause

P046E

EGR SENSOR B
(EGR sensor B circuit range/
performance)

ECM detects the following status continu-
ously for 5 seconds or more:
A difference between the output level of 
EGR pressure sensor and the differential 
pressure before and after EGR volume con-
trol valve calculated by ECM based on "tar-
get working factor of EGR" is bigger than 
specified value. 

• Harness or connectors

(EGR pressure sensor circuit is open or 
shorted.)
