Check injector resistance value integrity
for the relevant fault code, P0300 will
require all terminals listed to be checked:
P0301
- Engine ECM pin C23 to EMS relay pin
5
- Engine ECM pin B7 to EMS relay pin 5
P0303
- Engine ECM pin C6 to EMS relay pin 5
- Engine ECM pin B8 to EMS relay pin 5
P0303
- Engine ECM pin C7 to EMS relay pin 5
- Engine ECM pin B5 to EMS relay pin
OK
11.4

to 12.6
Ohms
Disconnect relevant
injector and proceed to test
6
Check relevant injector resistance:
- Injector pin 1 to injector pin 2
Renew relevant injector,
proceed to test 9
Check coil resistance value for the
relevant fault code, P0300 will require all
terminals listed to be checked:
P0301
- Engine ECM pin B33 to EMS relay pin 5
P0302
- Engine ECM pin B22 to EMS relay pin 5
P0303
- Engine ECM pin B11 to EMS relay pin 51
Renew relevant ignition
coil, proceed to test 8
Check relevant ignition coil resistance:
- Ignition coil pin A-1 to ignition coil
pin B-1
Renew relevant ignition
coil, proceed to test 9
Reconnect harness, clear fault code and
run engine to verify fault cleared.
Action complete - quit test
