2: Temperature sensor, 4V @ -20C
3: TPS signal input, 0.0 - at idle speed, Above idle speed
4: Drive position(auto), Battery voltage - R,D,1,2,3 , P,N, and manual
5: Signal Ground, 0.0 - Separate from power ground
6: Mass air flow, ground, 0.0 - Separate from power ground
7: Mass air flow, 2.0V @ Idling, 5.0V @ Full Load
8: Mass air flow, burn-off, 4.0 - At burn-off, 0 - In other cases
9: Power supply from main input 12V
10: AIC Valve, 6 - 11 at idle
11: Grounding point, 0 - Separate from power ground
12: TPS wide open, 0V @ wide open throttle, 5V @ Idling
13: Control signal Output, 7.1 Hz, 2.4-4.5 ms
14: Mass air flow sensor, approx. 2
15: Grounding point for coding, 0
16: Raising engine idle speed, 12V for A/C engaged, 0V for A/C disengaged
