Park Avenue V6-3.8L SC VIN 1 (2005)
IMPORTANT: This inspection is very important and must be done carefully and thoroughly.
Perform a careful underhood inspection when performing any diagnostic procedure or diagnosing the cause of an emission test failure. This can often
lead to repairing a condition without further steps. Use the following guidelines when performing an inspection:
-
Inspect all of the vacuum hoses for correct routing, pinches, cuts, or disconnects.
-
Inspect any hoses that are difficult to see.
-
Inspect all of the wires in the engine compartment for the following conditions:
-
Burned or chafed spots
-
Pinched wires
-
Contact with sharp edges
-
Contact with hot exhaust manifolds
BASIC KNOWLEDGE REQUIRED
NOTE: Lack of basic knowledge of this powertrain when performing diagnostic procedures could result in incorrect diagnostic performance or
damage to powertrain components. Do not attempt to diagnose a powertrain problem without this basic knowledge.
A basic understanding of hand tools is necessary in order to effectively use this section.
You must be familiar with some of the basics of engine operation and electrical diagnosis in order to use this section.
-
Basic electrical circuits-You should have an understanding of basic electricity and know the meaning of voltage (volts), current (amps), and
resistance (ohms). You should understand what happens in a circuit with an open or a shorted wire, and you should be able to identify a shorted or
open circuit by using a DMM. You should be able to read and understand a wiring diagram.
-
Use of digital multimeter-You should be familiar with the DMM, particularly the essential tool. You should be able to use the meter in order to
measure the voltage (volts), the resistance (ohms), the current (amps), intermittents (min/max), and frequency (Hertz).
-
Use of circuit testing tools-You should not use a test lamp to diagnose the engine controls system unless you are specifically instructed to do so.
You should know how to the use jumper wires in order to test the components and allow the DMM readings without damaging the terminals. You
should know how to use the J 35616 connector test adapter kit and use the kit whenever the diagnostic procedures call for front probing any
connector.
