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.

nissan maxima 3.5 camshaft position sensor or camshaft sensor
check engine light came on. played around with the car a little more. the
car stalls. when shifting to reverse hard shift. when placing car in D hard
shift. when you drive it, it starts off in 5th gear. when put into
tiptronic mode the shifter reads has gear 5. now when driving i have only 2
gears in tiptronic mode. im assuming 5 and maybe 3 or 4. later on that day
i turned the car on and everything went away, the hard crank, the stalling,
and the weird shifting. the next day i turn the car on and all of the
symptoms came back. i went to autozone and they read the ecm with a cam
shaft position sensor in bank 2 as the issue. my only question is would the
cam shaft positioning sensor cause the car to shift crazy and only have
reverse and 2 gears? and all the things i have mentioned? and is there a
way to reset the ecu to see if it really is a sensor or just a hiccup. im
all ears for sugestions before i bring it to the dealership and fork out
hundreds of dollars.

Ford Powerstroke Faulty Injector Wiring Harness
A faulty injector wiring harness on the driver's side cylinders of the
engine caused the engine to run the way it did in this video. I replaced
both wiring harnesses in case the other one failed. I also replaced all
eight glow plugs while I was at it. Runs perfectly now.

Bad Cam Angle Sensor (cas) on 2G DSM
A quick video documenting the typical 3-5 second idle/stall associated with
a bad Cam Angle Sensor. I started out with a short idle problem on my 1995
Talon TSI. The car would idle for about 3 seconds then stall. After
struggling to find a cause I was lucky enough to notice the CAS code
reoccurring on my OBDII Scan tool. This video is to help folks with this
problem identify, and perform the replacement of of the Cam Angle Sensor.

The Hardest Cold Start of a 7.3L Powerstroke On Earth. Taking nearly 6 minutes.
Ok maybe not THE hardest, but I believe it could possibly qualify.
ICP sensor leaking oil which in turn ruined the wiring harness. The
computer is ignoring the ICP totally here, and this is why it was starting
and running like this. When the computer ignores the ICP sensor the PCM
opens and closes the IPR abruptly, looking at other sensors (CPS, EOT and
EBPV) to determine what the ICP should be. Usually it sets it at 700 and
3000~ psi and that's it. I believe this is why it had such an un-stable
idle. Got a new sensor and wiring harness and all is well.
