INTAKE AND EXHAUST DIAGNOSIS

INTRODUCTION

M1151006900406

Intake leaks usually create driveability issues that
are not obviously related to the intake system.
Exhaust leaks or abnormal noise is caused by
cracks, gaskets and fittings, or by exhaust pipe or
muffler damage due to impacts during travel. The
exhaust leaks from these sections and causes the
exhaust noise to increase. There may be cases
when the system contacts the body and vibration
noise is generated.

TROUBLESHOOTING STRATEGY

M1151007000398

Use these steps to plan your diagnostic strategy. If
you follow them carefully, you will be sure that you
have exhausted most of the possible ways to find an
intake or exhaust system fault.
1. Gather information from the customer.

2. Verify that the condition described by the

customer exists.

3. Find the malfunction by following the Symptom

Chart.

4. Verify malfunction is eliminated.
