the lights flash in sequence to show dtc's (diagnostic trouble codes)

count the #of flashes and that is the # of the code

for example if u r having a problem w/fuel inj. or main relay

u should get 16 flashes then about a 3 sec pause then the code will

repeat unless there is more than one code so watch closely

every 3 sec pause indicates the start of next code

To find out what each code means, check this table:

1) Primary oxygen sensor- Defective circuit or unplugged/ Defective sensor

2) Oxygen sensor "B" - Defective circiut or unplugged/ Defective sensor

3) MAP (Manifold Absolute Pressure) Sensor - Defective circuit or unplugged/ Sensor

4) CKP (Crankshaft Position Sensor) - Defective circuit or unplugged/ Defective sensor

5) MAP (Manifold Absolute Pressure) sensor -Mechanical problem/ Disconnected piping

6) ECT ( Engine Coolant Temperature) Sensor- Defective circuit or unplugged/ Sensor

7) TP (Throttle Position) Sensor -Defective circuit or unplugged/ Defective sensor

8) TDC (Top Dead Centre) Sensor -Defective circuit or unplugged/ Defective sensor

9) CYP (Cylinder) - Defective circuit or unplugged/ Defective sensor

10) IAT (Intake Air Temperature)sensor- Defective circuit or unplugged/Defective sensor

12) EGR (Exhaust Gas Recirculation) -Defective circuit or unplugged/ Defective sensor

13) Atmospheric Pressure Sensor - Defective circuit or unplugged/ Defective sensor

14) IAC (Intake Air Control) Valve- Defective circuit or unplugged / Defective sensor

15) Ignition Output Signal - Missing or defective ignition output signal

16) Fuel Injector System - Defective circuit or unplugged/ Defective fuel injector

17) VSS (Vehicle Speed Sensor) - Defective circuit or unplugged/ Defective sensor

19) Automatic transmission lockup control Solenoid Valve- Defective circuit or unplugged/ Defective solenoid. A/T Only.
