 EGR Temperature Sensor Circuit
|
Circuit Description
The EGR temperature sensor is used to measure the temperature of the exhaust gas that exits the EGR cooler. This temperature is monitored to protect the engine against extremely high temperatures associated with the EGR system.
Component Location
The EGR temperature sensor is located in the air horn, on the intake side of the engine. Use the following procedure for a detailed component location view. Refer to Procedure 100-002 in Section E.
Shop Talk
This fault code can be caused by:
- A fouled EGR cooler
- High coolant temperature
- Low coolant level
- Malfunctioning EGR valve
- Malfunctioning EGR valve position sensor
- High exhaust temperatures
- Improper coolant-and-water mix
- Variable geometry turbocharger stuck closed.
Note: This fault code will probably not be active with no load on the engine in the shop. The engine must be loaded to trip this fault code and determine if the malfunction has been found and fixed.
