When car lack of power, you may doubt if the Ternary Catalysis blocked. For some cars, you can remove the Ternary Catalysis to check, but for most cars it's hard to remove, even removed it's hard to see how it is burnt inside.
Our test presure guage will save you from this trouble:
For a well running car, the front pressure of Three-way Catalyst is very low: 0.004MPa at idle; Less than 0.01MPa at 3000RPM.
If Three-way Catalyst slightly blocked, the pressure will go to 0.025Mpa or higher at 3000RPM; The higher the heavier it's blocked.
So you will know when you should exchange the Three-way Catalyst by reading the pressure.
Operation instruction:
1. Find the front O2 sensor
2. Remove it
3. Take off the test connector (the connector not included)
4. Screw the connector into exhaust pipe
5. Connect the tester to connector, start car and read the pressure data.
Note:
When car work normal, the pressure is very low, the pointer just move little; Only exhaust pipe blocked the pointer will move obviously.
Package included:
1 x Ternary Catalysis Pressure Guage (as the picture shown)
