Step
1. Install a scan tool.
2. Turn the ignition ON, the engine OFF and close
10 the throttle.
Does the Throttle Position (TP) sensor read less
than the specified value.
Compare the Engine Coolant Temperature (ECT)
with the Intake Air Temperature (IAT).
11
Is the ECT relatively close to the IAT?
1. Check if the Manifold Absolute Pressure (MAP)
sensor reading is over the specified reading.
2. Crank the engine while watching the MAP sensor
12
reading.
Does the MAP sensor read above the specified val-
ue and then change while cranking the engine?
Crank the engine.
13
Does the Crankshaft Position (CKP) Active Counter
increment while cranking?
Check the scan data for serial data.
14
Was serial data lost while cranking the engine?
Repair voltage loss to the
engine control module (ECM) from the igni-
15
tion switch.
Is the repair complete?
Check for the presence of spark from all of the igni-
tion wires while cranking the engine.
16
Is spark present from all of the ignition wires?
1. Measure the resistance of the ignition wires.
2. Replace any of the ignition wire(s) with a
resistance above the value specified.
17
3. Check for the presence of spark from all of the
ignition wires.
Is spark present from all of the ignition wires?
1. Turn the ignition OFF.
2. Disconnect the Crankshaft Position (CKP) sensor
connector.
3. Turn the ignition ON.
18
4. Measure the voltage between the CKP connector
terminals 1 and 3.
Does the voltage measure near the value specified?
Measure the voltage between the CKP connector
terminals 2 and 3.
19
Does the voltage measure near the value specified?
Measure the voltage between the CKP connector
terminals 1 and ground.
20
Does the voltage measure near the value specified?
Measure the voltage between the CKP connector
terminals 2 and ground.
21
Does the voltage measure near the value specified?
