How to solve the problem that the engine oil temperature voltage is higher than normal?

Kyotechs teaches you how to find the problem of engine oil temperature voltage higher than normal. Is it the problem of ECU, wiring harness, or sensor? Let us help you detect it with professional instruments.

（Detailed video explanation）

Customer has the oemCaterpillar E325C that it has error code 175-3 

and customer complain

they have the error code for the 175-3 and the engine oil temeperture votage above normal (circuit break)

temperature sensor problem

We have to see this is our ECU problem

Harness problem or sensor problem

Let me show you

And this ECU

Later this one we need to check reference book

We need to see the No.18(grounp harness) and No.18 and 34 harness (5V voltage and can harness for communition)

and one harness is the signal harness(cummication harness) for 5 voltage

Voltage and another one 18 is the ground harness

now we will check this one

see this one they have the 5V offer because the ECU can offer 5V,It is mean ECU and engine harness is ok

We see have the 5V it means ECU is okay harness is okay they have the offer the 5V can offer to the harness

and normal because this one is connected

this is we normal check you use this one

this the position long they will dash 5V voltage

so we firstly we check the connector have the 5V or not 

if they have the 5V the harness is okay ECU is okay

we get the signal just like we add the engine oil temperature sensor fencer and the signal you see is a disappear, 175-3 is miss

and it's disappear and now we can offer them to the give them the signal just like the omega

we can change it means the sensor is okay, we just the same offer same the sensor

but this sensor we can adjust the omege if the sensor is ok, error is missing for 175-3
