If the sensor is a 5V sensor that draws little current, like a MAP sensor, connect its power, signal and ground connections to the buffer circuit assembly. If the device, such as a wideband, has it's own power and ground, connect only the signal wire to the device. Insulate any unused wires. | If the sensor is a 5V sensor that draws little current, like a MAP sensor, connect its power, signal and ground connections to the buffer circuit assembly.

Again, the EGRTemp on a 1G and the Baro input on a 2G are problematic for some aftermarket sensors. When feeding certain wideband kits into the EGRTemp input on a 1G, for example, you may see normal A/F ratio readings above 11.5:1 but then the readings flatline there and won't show any value below that. | Again, the EGRTemp on a 1G and the Baro input on a 2G are problematic for some aftermarket sensors.
