AIR INTAKE/EXHAUST

TESTS

These air intake/exhaust

system tests can be run any time you think there may be a problem

with the air intake or exhaust systems, or if you were sent here from another test.

At the bottom of this page is a simplified block diagram of the intake air/exhaust system.

A detailed functional flow is not applicable to this system.

The air intake/exhaust

system is a very simple system that can cause very annoying

problems.

Whether the vehicle is hard to start or runs rough or never develops full power,

it’s worth the few minutes that it takes to check the components of this system.

You can run

through the diagnostic logic for this system almost any time you open the hood or check the

underside of your vehicle.
