Default Preventive Maintenance Items - Sensors

Hi All,

Would you say camshaft position sensor and crankshaft position sensor are preventive maintenance items or just spare parts to carry? I never changed them in my 2004 T1N and was wondering if changing them would be a good idea and carry the old ones as spares. Both are currently working fine. Or just carry the new ones as spares. What are your thoughts?

Sensors are not preventative maintenance items.

Sensors are not preventive maintenance but you definitely want to be able the remove the crankshaft position sensor BEFORE it fails. They can be hard to get out of the hole and It got me stranded in a bad spot trying to get it out. I started a thread about how to remove it the easy way if it is stuck. After that, just keep a pair of 1 cam and crank sensor and you are good to go.

I agree with woody.. not prev maintenance items but if a crank sensor fails and you’ve never swapped one it can be a pain in the butt. Also, OEM only on the sensors. No autozone Chinese or the like sensors...

Since some time in 2008 I've carried too many sensors just in case. Some I have swapped in just to test. Others are still untouched. Not one has been needed to date to keep on traveling... to avoid jinxing myself knock/touch wood.

If you have the sensors and are inclined to put in the time, swap in the new unit and carry the removed as your spare. That way you know that both are the properly working parts.

I don't have the thread link, but there's information out there about removing a spot welded and glued floor tunnel panel for easier access to the Crankshaft Position Sensor CKP. Worth keeping in mind if stuck.

I think Woody and Vanski have already covered it.

When's the last time a light bulb went out in your house and stranded you 137 miles from the nearest auto parts store?

I carry spares of almost everything I can think of but need to add those two sensors to my traveling toolbox. Thanks for the reminder.

I never said there was anything wrong with carrying spare parts.

The OP's question was whether he should replace sensors as preventative maintenance, to which the obvious answer is "no".
