Replacing the knock sensor, 4th gen Maxima (part 1 of 2)
How to replace the knock sensor in a 4th gen Maxima, part 1 of 2. Part 1 goes over how to use a ratchet and lots of extensions to get to the knock sensor bolt.
Part 2 goes over how to use the wrench and prying tool (screwdriver, prybar, etc) to loosen the bolt.
Yes, I said 'pain in the ass' what, 8 times? I must've edited out another half dozen.

Replace rear strut mounts, 4th gen Maxima
How to remove and replace the rear strut mounts on the 4th gen Maxima. This will work for strut replacement as well, or any other reason for you to tear down the rear struts.
You'll need a spring compressor (unless you are installing pre-assembled strut assemblies), 12mm socket for the strut mount-body bolts, 14mm socket for the upper strut mount retaining nut, and a 17mm socket for the lower strut mounting bolt.
Replace spark plugs/coil packs on a 4th gen Maxima (updated video)
How to remove and replace the spark plugs/coil packs on a 4th gen Maxima.
This is an updated video to replace the one from a few years ago that was completely washed out and didn't really cover the subject as well as I would have liked.
Tools required are a 8mm socket (or phillips head screwdriver), 5/8" plug socket, extensions, 4mm allen key/bit socket for the front coil cover bolts, and a 12mm socket for the EVAP CPVCV (if so equipped).
Removing/replacing coils and spark plugs, 4th gen Maxima (outdated)
How to remove/replace the coil packs and spark plugs on a 4th gen Maxima.
Video isn't nearly as in-depth as the other ones, and it's also very washed out (my camcorder sucks in the daylight). Probably end up redoing this one at some point in the future, possibly going through replacing all 6 with gapping, and certainly when it's darker out.
This is an outdated video, I have since uploaded an updated video here: http://www.youtube.com/watch?v=DsDLHULZbsE
Knock Sensor Operation

Explains the Knock Sensor Operation and Testing. The Knock sensor is a actual microphone screwed into the engine block. It is tuned to listen to the exact frequency of an engine knock, which is a high frequency ping. A failing knock sensor will cause all sorts of problems to engine operation, such as skewed timing controls, loss of performance and power and ever the system going to linp-in mode. Learn how it works and how to test this incredible component. (note: We allow all schools and training institutions to use our software free of charge, so long as it is not sold to others.

How to Change a Oxygen on a Engine - Nissan frontier oxygen(O2) sensor service
In this video we show How to replace the oxygen (O2) sensor on the Nissan Frontier V6 engine.Here you will see the difference between Bank #1 and Bank #2 heated (4-wire) oxygen sensors. Replacing the oxygen sensor every 60-70,000 miles is an effort to help conserve fuel/gasoline.The oxygen sensor are not the only device to harness against waste consumption.

As with the plugs video, it's a bit washed out, and not very detailed. Pretty much just an overview, I'll remake this video at a later date.
Remove/replace evaporator, 4th gen Maxima
How to remove and replace the evaporator box on a 4th gen Maxima. Didn't have enough time to get into splitting the box and replacing individual components, but once it's out it's very easy.
How to replace an O2 Sensor and save money.
I show you how to replace your O2 Sensor. This is being performed on a 1997 Chevy Tahoe. Automotive oxygen sensors, colloquially known as O2 sensors, make modern electronic fuel injection and emission control possible. They determine if the air fuel ratio exiting a gas-combustion engine is rich (with unburnt fuel vapor) or lean (with excess oxygen).

2003 Nissan Altima S - Camshaft & Crankshaft Position Sensors
2003 Nissan Altima S 2.5L W/Automatic Transmission
INTERMITTENT NO-STARTS & ROUGH-STARTS WITH NO DTCs SET.
A LOCAL AUTOSHOP HAD REPLACED ONLY THE CAMSHAFT POSITION SENSOR, MADE SURE NO DTCs PRESENT AND OPS CHECK GOOD.
HOWEVER, THE PROBLEM RETURNED.
NOW, THE SAME AUTOSHOP BELIEVES THAT THE FAULT IS WITH THE TRANSMISSION FLEX PLATE, WHICH MAY HAVE DAMAGED THE CRANKSHAFT POSITION SENSOR AS WELL, ACCORDING TO HIM.
ESTIMATE IS AT ~$750.
The mechanic didn't try to replace the Crankshaft sensor alone, he went straight for the Tranny drop. I figured go with the cheap fix first. If it comes back, then we will look into the Flex Plate.
I replaced the recently replaced Camshaft sensor & the never been replaced Crankshaft sensor. So far, so good.
Replacing the Camshaft sensor is a 2-minute job.
The Crankshaft sensor will likely take 30 times as long.
It seems like the Old Crankshaft Position sensor I removed was a bit high on a resistance check, when compared to brand new sensors. With too high a resistance value, the sensor may not make use of the full voltage it is receiving and/or it may not return the required amount of voltage to the Powertrain Control Module (PCM), which will lead to irregular engine operation or a no-start condition.
Both Camshaft & Crankshaft sensors are the same part number. The 3rd version of the sensor is encased in metal, not plastic.
The OEM part number is 23731-6N21A ($44 us)
The old part numbers were encased in plastic. These part numbers should not be used: 23731-8J005 & 23731-8J006

Nissan recalls that problem to reprogram the ECU. What happens the crank sensor electrical terminals seep oil into the crank sensors plug. The new metal crank sensors correct this problem. Location of this sensor on the back of the motor is difficult to change and you need gorrilia finger grip to depress the connector green lock and remove the sensor. Depending on your cars Vin# Recall Campaign # R0712 NHTSA# 07V-527. Hopefully your factory warranty replaces the sensor no charge 5yr/60,000 mile. The campaign only covers the ECM reprogram. The ECM reprogram makes both sensors act as one so either will allow the car to start. Stalling and not starting is a safety risk.
