Well I'll do it. The Sentra SE-R included during the early 90's production year has a problem with the degradation of the MAF sensors ground wire. It causes the computer to put out a higher voltage signal in order to reach what it deems as a reference voltage in order to compensate for the ground wire. Well that's not you question. Reground refers to putting in a new ground wire to fix this common problem. Don't cut out the stock one simply instal a new one. Here's an abridged version. Remove the MAF sensor harness from the sensor at the airbox union. Identify the ground wire with a digital multi meter. Strip the insulation as close to the terminal as possible or remove that wire from the harness. Solder a new wire of 16 AWG or larger. Route this wire along the same path to the common muti ground point on the intake manifold. Crimp or solder a ring terminal to the end of the new wire and ground it to the exact same spot as the original wire. The ECU somehow references this point with a certain learned voltage signal to take readings for ground on many engine sensors. Viola all done. Good luck' Ben H. Baird '91 SE-R
