07 Tahoe 5.3l auto 99k

My wife was driving home and it started bucking. It displayed the service stableliltrak, service traction control and the service engine soon light came on. I pulled P0335 Crankshaft position sensor circuit malfunction. I reset the code and it hasn't come back this week.

Should I order the sensor and just replace it or just wait until it comes back?

I'd check the wiring and grounds. For those to go out like that, which are not related to each other, is strange. I don't know about full size, but on the 360's, the ignition switch could cause something like that and is a known failure prone part.

It came back after a week. I looked around with the multimeter, nothing seemed off. The crank position sensor is up above the starter so I figured if I was going to get in that far I might as well replace it. 13mm socket on a 12inch extension for the starter bolts and a 10mm socket on the extension from the wheel well for the sensor made the job simple.

I would too for good measure. The sensor maybe sticking.

Just hope you don't have to get a CASE relearn as that's what usually happens when you disturb that sensor.

I pulled the battery cable off before I started. I left it off for an hour. It has been a week. So far so good.
