A normal car has a very low SCR/DOC/PDF box pressure, which is 0.015MPa or 0.15kg/cm at idle speed ² 。 Not exceeding 0.03MPa or 0.3kg/cm at 2500 rpm ² , If there is a slight blockage in the SCR/DOC/PDF of the car, the exhaust pressure will increase to 0.5MPa or 0.5kg/cm at 2500 rpm ² Even higher, the higher the pressure, the more severe the blockage. Based on this data, we can determine whether to replace or clean SCR/DOC/PDF 

Usage Method

Step 1: Find the upstream temperature sensor.

Step 2: Remove the upstream temperature sensor.

Step 3: Remove the detection connector.

Step 4: Twist the detection joint into the exhaust pipe by hand

Step 5: Insert the detection table, start the vehicle, and read the data

Note: The exhaust pressure of a normal vehicle is very low, and it is normal for the pointer of the detection meter to only move slightly. The pointer only rises to half or full when the exhaust pipe is blocked. You can blow air into our watch with your mouth, and the pointer will rise.
