Infinity Pin Hrdwr Ref. Hardware Specification Notes
C2-20 Analog_In_15 12 bit A/D, 100K pullup to 5V 0-5V analog signal. Use +5V Out pins as power
supply and Sensor Ground pins as the low
reference. Do not connect signals referenced to
+12V as this can permanently damage the ECU.
Normally used as Exhaust Back Pressure input.
C2-21 Analog_In_16 12 bit A/D, 100K pullup to 5V 0-5V analog signal. Use +5V Out pins as power
supply and Sensor Ground pins as the low
reference. Do not connect signals referenced to
+12V as this can permanently damage the ECU.
Normally used as DBW1_TPSB input.
