Perform an On-Board Diagnostic (EOBD) System
Check.
1
Is the system check complete?
1. Ignition OFF, disconnect the
engine control module (ECM).
2. Ignition ON, check the 5 volt reference circuit for
the following conditions:
Poor connection at the ECM.
2
Open between the ECM connector af-
fected sensors shorted to ground or voltage.
3. If a problem is found, locate and repair the open
or short circuit as necessary.
Is a problem found?
1. Check the sensor ground circuit for the following
conditions:
Poor connection at the ECM or affected
sensors.
3
Open between the ECM connector and
the affected sensors.
2. If a problem is found, repair it as necessary.
Is a problem found?
Measure the voltage between the Exhaust Gas Re-
circulation (EGR) Pintle Position Sensor signal cir-
cuit at the ECM harness connector and
4
ground.
Does the voltage measure near the specified value?
Measure the voltage between the Manifold Absolute
Pressure (MAP) sensor signal circuit at the
5
ECM harness connector and ground.
Does the voltage measure near the specified value?
Measure the voltage between the Throttle Position
(TP) sensor signal circuit at the ECM harness
6
connector and ground.
Does the voltage measure near the specified value?
Measure the voltage between the Intake Air Temper-
ature (IAT) sensor signal circuit at the ECM
7
harness connector and ground.
Does the voltage measure near the specified value?
Measure the voltage between the Engine Coolant
Temperature (ECT) sensor signal circuit at the
8
ECM harness connector and ground.
Does the voltage measure near the specified value?
1. Disconnect the EGR valve.
2. Measure the voltage between the EGR Pintle
9 Position sensor signal circuit at the ECM
harness connector and ground.
Does the voltage measure near the specified value?
Measure the voltage between the Transmission
Fluid Temperature (TFT) sensor signal circuit at the
10
ECM harness connector and ground.
Does the voltage measure near the specified value?
