Continuous Trap Oxidizer: Testing and Inspection
Trap Oxidizer Test1. Connect exhaust gas back pressure test gauge to the test port on exhaust manifold. Place the transmission in park, start engine and increase the RPM to 3,000, and read the pressure. If the pressure is 18.9 psi (1.3 bar) or less, the pressure is ok, test is over. If the pressure is above specifications, proceed to step 2.
2. With the shift lever in position "2", either run the vehicle on a dynamometer or the road for one minute, varying the throttle from part to full throttle. Go to full throttle for 2 minutes and check the pressure. If the pressure is within the specifications listed in the previous step, the exhaust system is ok, test is over. If not, repeat the test and replace the trap oxidizer as required.
