Engine sensor failure on the 2001 Nissan Maxima

Only 1 report for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.

When engine sensor failure gets reported

There are 4 reports of engine sensor failure on the 2001 Nissan Maxima, 1 with a mileage attached. That is too few to place the failure on the odometer with any confidence.

A part like this is normally expected to survive 95,000 miles. It is the 15th most-reported problem on this model year.

The whole distribution

Percentiles of the 1 odometer readings owners gave.
10th25thMedian 75th90th
— — 100,000 miles — —

Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.

What a percentile can and cannot tell you here

These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.

What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.

Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.

What happens, and what it costs

Putting it right typically runs $180–$900 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.

The same failure on other years

The same failure is reported on 10 model years of this car. It shows up earliest on the 2009, at a median of 15,000 miles, and latest on the 1997 at 135,000 miles.

By volume the 2000 carries the most reports, with 16; the 2001 has 4. A mode that appears across most years of a model is usually a design choice rather than a bad batch.

If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote

Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.

Tl*the contact owns a 2001 nissan maxima. At 55 MPH the vehicle suddenly shut off. The vehicle was towed to a local mechanic, who diagnosed the failure as the mass air flow sensor. The replacement part was ordered from the dealer, but the new sensor also failed. The diagnostic test showed that the sensor needed to be reprogrammed. The contact towed the vehicle to the dealer, who stated that the engine motor mounts short-circuited the aac which caused it to blow. Once the aac failed the electric shock blew out the emc. In order to properly repair the vehicle the contact must pay almost $3,000. The contact stated that when the key was put in the ignition and the accelerator pedal depressed the vehicle operated normally. However, as soon as the pedal was released the car shut off again. The current and failure mileages were 100,000. *ak

How far this goes

This page is kept out of search results because 4 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.

Complaints are voluntary, so 4 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.

Questions this page answers

At what mileage does engine sensor failure happen on the 2001 Nissan Maxima?

Across 1 owner reports that included an odometer reading, half were filed by 100,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is engine sensor failure on the 2001 Nissan Maxima?

4 reports have been filed with NHTSA, about 0.1 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.

What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
