Question about 2001 Nissan Sentra

1 Answer

2001 Nissan Sentra 1.8 l engine won't start.

I have replaced several sensors (mass air flow sensor, cam) the computer, plugs. This still hasn't solved the problem. When I do get it to start it will not accelerate properly. It misses a lot and it will go dead. Please help me. Could it be the injectors or something to do with the fuel system? Broke from buying parts that won't fix the problem.

Is the check engine light on?? You may have a stretched timing chain, but the only way to check that is to remove the valve cover and look at the timing chain tensioner to see if it is way out of the housing. We see chains on those stretch and cause a running issue like the one that you are descibing, because its out of time. Just a pointer, not a solution, but something worth looking into.

Check the fuel filter. Do keep in mind that the fuel system is 'always' under pressure!!! Also check EGR. Your fuel pump must be working or it wouldn't start at all. The C02 sensor could be part of the prob. A real bugga to change! But should be changed every year. Do start with the filter, then move on. You have spent enough already! Frankster016

Poor acceleration, but the engine is strong


your ECM/ computer may be shot. those model sentras had campaign, where the ECM box would be lined with foam to hold the computer tight, but the fumes from the glue that Nissan used to hold the foam down, would eat the computer internally and destroy it. Nissan had us pull those foams out and discard. if you still have the foams inthere, good chances are that the ECM is fried, causing issues. Question: did you use aftermarket air filter in the air box?? or Nissan filter?? Let me know. very important to use Nissan filter it this car.

2001 Tacoma running rich but the scanner is reading a lean code


No, disconnecting the sensor and seeing no change would be a indication the maf was bad. Your computer takes information from your mass air flow sensor (maf), o2 sensor, cam position, and knock sensor to regulate the correct mixture. I would suspect a bad o2 sensor upstream. Try taking off the o2 sensor and seeing if there is black carbon on the base of the o2 sensor. If it has black carbon on the base it could be a bad o2 sensor. This problem could also be easily solved by hooking up a mechanics diagnostic computer to pin point the problem. Sometimes, you can clean the mass air flow with a special cleaner to help it generate a more accurate reading.

HOW TO INSTALL MASS AIR FLOW SENSOR


The Sentra is known to blow mass airflow sensors. If you bought an aftermarket sensor and it says to reprogram the computer you are pretty much out of luck. If it were me I would read the instructions again as it probably means that you have to disconnect the battery for five minutes and let the computer learn the new mass airflow sensor.

The mass airflow sensor, or MAF sensor, measures the amount of air flowing into the engine through the air intake. The sensor on your Nissan Sentra is located in the air intake tubing that runs from the filter to the fuel injection system. If your Sentra is idling rough, has problems starting and frequently stalls during normal driving, it is likely that the MAF sensor is failing and needs to be replaced.

jQuery('.intro .thumbnail').each(function(i,e){ jQuery(e).find('img').one('error',function(){ jQuery(e).remove(); }); }); Difficulty: Moderate

Things You'll Need:
  • Socket wrench and socket set Screwdrivers (Philips and slotted) New MAF sensor
Instructions
  1. Open the hood and locate the air box. It should be on the passenger side of the engine bay near the front of the vehicle. It will be a plastic, box-shaped object with a large plastic pipe running to the back of the engine.
  2. Examine the new MAF sensor. You'll be looking for this component in the air box.
  3. Remove the air box cover and pull the air filter out.
  4. Loosen the band clamps on the intake tubing with a screwdriver and pull the intake tubing off of the air box.
  5. Unplug the electrical connection to the MAF sensor and pull the MAF sensor out of the air tube assembly.
  6. Install the new mass airflow sensor and put the air box assembly back together. Installation is the reverse of removal.

Hope this help to solve your problem (remember comment and rated this).

Car will not move


did you replace the MAF mass airflow sensor ? If you did not, clean it with electronics cleaner so it won't damage the sensor. that could be the cause. also the EGR vavle would cause a problem like that.
