No parts should be replaced for these fault codes unless a definite sensor
failure is found.
Fault Tracing Procedure:
1. Allow the vehicle to sit until the engine and exhaust have reached
ambient (air) temperature.
2. Turn the ignition to ON, engine OFF.
2. Using Premium Tech Tool (PTT), run either of the operations below:
• 2545-08-03-02 Exhaust Aftertreatment Diagnostics, option A
- This will provide a numerical view of exhaust temperatures.
• 2589-08-03-02 Exhaust Aftertreatment System, Service
Regeneration
- This will provide a graphical view of exhaust temperatures.
3. Ensure that the sensor readings are within 10 °C (18 °F) of
one another before starting the engine.
4. Start the engine.
5. Monitor exhaust temperatures on PTT:
• The sensor temperatures should rise in the order of 1, 2, 3, 4 as
shown below after starting the engine.
6. Evaluate results:

in the correct order when the engine is running: No further fault
tracing should be performed. Clear the DTCs and return the vehicle to
service.
• If one or more sensors are displaying a different reading from
the others or are spiking instead of smoothly increasing with the
engine running: The sensor(s) should be suspected to be faulty.
• If the temperature sensor values rise out of order: The sensors
should be checked to ensure they are installed in the correct positions.
An example of proper temperature sensor function when engine is cold
(shutdown overnight). All 4 temperature sensors are expected read within
10F of each other and ambient temperature.
Once engine is warmed (idle for few minutes), taking vehicle to high idle
(>1000rpm) typically should show temperatures similar to picture below.
T1 > T2 > T3 > T4.
NOTE: T4 is only valid for OBD19 and Newer Vehicles.
