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.

Crank Position Sensor Replacement - Stalling 3800 3.8 Engine
If you have a vehicle with the GM 3800 Engine which stalls randomly and may
not always restart, then you likely have a bad crankshaft position sensor.
If your vehicle runs perfectly but the tachometer sometimes registers
incorrectly then you should replace this sensor ASAP before it leaves you

I enjoy the process of testing theory because you always learn something
new, regardless of the outcome.
Using a spark plug defouler kit, I install a "buffer" in between the
downstream oxygen sensor and the catalytic converter. Quite often,
frustrated car owners get the P0420 code for reasons other than a bad cat.
I have heard of people getting the code just because they removed the
converter and reinstalled it. It can also happen if you run your vehicle
out of gas etc... etc...
It is also common for car owners to get the P0420 code, replace the
converter, and both o2 sensors-- only to have the code come back after 1000
miles or so. This can be a very frustrating, time consuming and of
course-- expensive venture. Here is one way to resolve the issue. Good
luck and have fun!
