1g Code Reader - CEL CODE READER
This is a How-To on figuring out your Check engine light(CEL) for 1g.
Tools:
Volt Meter or LED
Connection:
Connect the positive of the volt meter or LED to pin #1 and the ground to #12 pin on the port. SEE PIC.
After you got that done, turn your key to the ON position and watch the pulse.
A long pulse counts as 10, a short pulse as 1.
1 long pulse: Engine Control Unit ( ECU )
pulses 1 by 1: Normal operation
Codes/pulses:
11. Oxygen Sensor
12. Air Flow Sensor
13. Intake Air Temperature Sensor
14. Throttle Position Sensor
15. Motor Position Sensor
21. Engine Coolant Temperature Sensor
22. Crank Angle Sensor
23. No 1 Top dead center sensor
24. Vehicle Speed Sensor (Reed Switch)
25. Barometric Pressure Sensor
31. Detonation Sensor
36. Ignition Timing Adjustment Signal
41. Fuel Injector
42. Fuel Pump
43. EGR (California) ((This is also a common code when the ecu capacitors have to be replaced.))
44. Ignition Coil ((This is also a common code when the ecu capacitors have to be replaced.))
