Section 17 (Engine Controls W/O Codes - 2.4L Engine): Introduction

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 1997 Pontiac Sunfire, 1997 Pontiac Grand Am, 1997 Oldsmobile Achieva, 1997 Chevrolet Malibu, and 1997 Chevrolet Cavalier. However, it is still accessible from the selected car via links, so may be relevant.

Before diagnosing symptoms or intermittent faults, perform basic diagnostic procedures in the BASIC TESTING - 2.4L article and diagnostic steps in the TESTS W/CODES - 2.4L article. Use this article to diagnose driveability problems when a current trouble code is not present.

Symptom checks are intended to direct the technician to malfunctioning component(s) so that further diagnosis may be performed. A symptom should lead to further testing of specific components or systems, or verification of adjustment specifications.

Use intermittent test procedures to locate intermittent driveability problems that do not occur when the vehicle is being tested. These problems may cause a noticeable driveability problem or cause the Malfunction Indicator Light (MIL) to illuminate on some vehicles.

It is also possible that certain driveability concerns have been rectified by the manufacturer through substitution of a revised PROM or Powertrain Control Module (PCM). Check with manufacturer for latest information on updated PROMs and PCMs.

NOTE: For specific testing, see SYSTEM/COMPONENT TESTS article. To verify specifications, see the ADJUSTMENTS - 2.4L or appropriate SPECIFICATIONS article.
