P1184 Engine Oil Tamp Sensor Circuit Performance

What does it mean, and what do i have to replace?

Thanks

 

DB9 DIAGNOSTIC TROUBLE CODE (DTC) OR P1184
DTC P1184 indicates that the engine oil temperature is not warm enough to perform a KOER Cylinder Contribution Self Test. The engine oil temperature must be greater than 20°C or 68°F (3.82 volts).
Possible causes:
engine not fully warmed up
low oil level
cooling system failure
worn or damaged EOT sensor
faulty thermostat
EOT sensor circuit failure

 

What are you checking the codes with? Can you read the EOT temp?

 

Yes I can check the EOT

 

Was the engine warmed up when it set the code? Were you running the CCT on it when you got the code? Clear it and see if it returns.

 

I have 2 or three injectors that doesn't pass buzz test, and the same for the cc test, but the truck runs fine

 

Are the injectors #3 and #8?

 

Gotta run. But I will try to help you figure this later if you haven't already.
