How to Cure Nissan Altima /Sentra 2.5 Code P0355 Cam/Crank Position Sensors includes Rough Idle and Stalling
Do you have error code P0335? Is your car running rough dying at stoplights? You most likely need the New design Genuine Nissan Heat shielded Crank and Cam position sensors. This is a very common problem on 2000-2006 Sentra and Altima with the 2.5 Liter Engine. The car can die without warning when idling, or if you are one of the lucky ones, you will experience really rough idle as a warning they are about to go out.
The instructions below will help you to install the sensors, you will need to replace both as they work together, and not replacing both will ensure more problems down the road. Nissan has updated the sensors to be much more heat resistant. We recommend the Genuine Nissan Sensors, as the sensors auto parts stores such as Auto Zone, and Advance Auto Parts are selling are not heat resistant and fail quickly.
Installation Instructions and tips:
1- ***Do not use magnets or place the new sensor(s) close to magnetic materials.***
2- Disconnect the negative battery terminal (it may also help you clearing the codes).
3- Un-clip the Air Filter box, disconnect the Intake clamp at the Electronic Throttle Control Actuator, also disconnect the Mass Air Flow Sensor grey electrical connector, and with care remove & handle the Intake (since MAF Sensor is there!). The PVC Hose should come out easily without using a tool, simply remove the whole Intake.
4- Disconnect the green connector at the Electric Throttle Control Actuator, and move it safe close to the hoses by the firewall.
5- You can use one of those gloves which protect almost your whole arm.
6- Use a mirror which you can sit near the location of the sensor, it saves time for first timers.
7- Carefully use a flat headed screwdriver to push-in and unlock the green Crankshaft Sensor connector
8- It may be easier to un-bolt/screw the plate holding the wire using a 12mm socket, this way you have another access route.
9- Un-bolt/screw the sensor with a 10mm socket, is supposed to be only one bolt/screw. Use your favorite combination: extension, ratchets, what works for you.
10- If the sensor is hard to remove, move the sensor internal thread location at twelve o’clock, and use a flat 9/16 wrench circular head to remove it easily. Better if you have one with twin heads to use with a screwdriver.
11- When inserting the Crankshaft wire connector, make sure it locks as intended, otherwise slide back its white head.
***Reminders, handle the new sensor(s) with care, again isn’t recommended placing the sensor(s) close to magnetic materials. Also the Crankshaft sensor is the one with a white mark.***
