Preliminary Checks

WARNING: This page is about a different car, the 2006 Suzuki Verona. However, it is still accessible from the selected car via links, so may be relevant.

Before using this section you should have already performed the On-Board Diagnostic (OBD II) System Check .

Perform a thorough visual inspection. This inspection can often lead to correcting a problem without further checks and can save valuable time. Inspect for the following conditions:

Engine Control Module (ECM) grounds for being clean, tight, and in their proper location.
Vacuum hoses for splits, kinks, collapsing and proper connections as shown on the Vehicle Emission Control Information label. Inspect thoroughly for any type of leak or restriction.
Air leaks at the throttle body mounting area and the intake manifold sealing surfaces.
Ignition wires for cracks, hardness, proper routing, and carbon tracking.
Wiring for proper connections.
Wiring for pinches or cuts.
