TROUBLESHOOTING (DTC P0403/DTC No.51)

Step

Action

Yes

No

1

Was “Engine Diag. Flow Table” performed?

Go to Step 2.

Go to “Engine Diag. 
Flow Table”.

2

EGR  Valve  Check  :

1) With ignition switch OFF, disconnect connector 

from EGR valve.

2) Check for proper connection to EGR valve at 

each terminal.

3) If OK, check EGR valve for resistance referring 

to “EGR System” in Section 6E2.

Is check result as specified?

Go to Step 3.

EGR valve malfunction.

3

Wire Harness Check :

1) Connect connector to EGR valve.
2) Remove ECM (PCM) cover and disconnect 

connector from ECM (PCM).

3) Check for proper connection to ECM (PCM) at 

system related terminals.

4) If OK, check for resistance between following 

terminals of ECM (PCM) connector discon-
nected.

EGR valve resistance
C51-2-16 and C51-2-21, C51-2-17 and C51-2-21,
C51-2-4 and C51-2-21, C51-2-5 and C51-2-21
: 20 – 24 

Ω

 at 20°C, 68°F

C51-2-16 and ground, C51-2-17 and ground,
C51-2-4 and ground, C51-2-5 and ground
: Infinity (

∞

)

Is check result as specified?

Intermittent trouble or 
faulty ECM (PCM).
Recheck referring to 
“Intermittent and Poor 
Connection” in Section 
0A.

“BLU/BLK”, “LT GRN”, 
“LT GRN/WHT”, “LT 
GRN/YEL” or “LT GRN/
RED” circuit open or 
shorted to ground.
