Question about 2000 Nissan Sentra
No power going up hills cuts out while driving mostly over 40mph. first code was for fuel level sensor. now getting codes for maf o2 vss and heater circuit sensors. car just started not starting tightenened loose neg cable but just noticed second half of cable where they meet with clip has broken wires help
You prpbably need a new ECM/computer. Nissan had a problem with the ECM box and the foam inside the box. The glue, which Nissan used to attach the foam onto the box EATS up your computer internaly. The vapors from the glue it self damage the ECM/computer. Nissan actually has a campaign to remove the foams out of the ECM box. By the way ECM has 80000 mile warantee, so if your car has less than that, Nissan will replace it for free. I see it all the time. Sentra with heater circuit code
needs an ECM 95% of the time.

Fix the broken wires their probably the problem then if problem still present check fuel pump.......... you can bench test it by putting power and ground to the right wires don't be scared you wont hurt anything
