    P0335 - good sensor and wiring; next probable cause?

    This is great information. It'll take me a week or so to get everything together, but I'll post back as soon as I can and update the status. Thanks a million.

    P0335 - good sensor and wiring; next probable cause?

    I just saw your comments about the battery. I didn't realize the computer controlled the alternator - I expected some electronic parts that controlled the charger, but not this computer. Maybe this is a separate question, but what's your thought about purchasing a used computer off of eBay. I...

    P0335 - good sensor and wiring; next probable cause?

    1. Ignition OFF, disconnect the harness connector at the CKP sensor. 2. Test for less than 1 ohm of resistance between the CKP low reference circuit terminal B and ground.  If greater than the specified value, test the low reference circuit for an open/high resistance. If the circuit tests...

    I don’t know the exact age. Maybe 4 years?

    P0335 - good sensor and wiring; next probable cause?

    I'll also note that I've not seen a correlation between the setting of the P0335 error code and lower voltage. I've specifically wondered about that, and we've been logging in a notepad every time this error code pops up, but at this time they've never occurred at the same time - they both occur...

    P0335 - good sensor and wiring; next probable cause?

    Sorry about that - I had a phone call come in and lost my train of thought. My multimeter normally shows 13.6 V across the battery terminals, but it drops down to 12.7 V when the battery gauge is reading on the lower side. This may occur for 5 minutes or so, and then it goes back to normal. I've...

    P0335 - good sensor and wiring; next probable cause?

    I used an oscilloscope I had temporary access to, and I saw the CMP and CKP pulses on the same screen, so I did see the live plot. I even manually turned the engine and watched the CMP and CKP signals. I don't know of anyone with a Tech2 scanner. Will that provide other information than the...

    P0335 - good sensor and wiring; next probable cause?

    We have a 2007 Yukon XL 1500 5.3L with 220,000 miles. We're having a chronic problem with the crankshaft position sensor code lighting up, causing the Yukon to throw the stabilitrak warning and then goes into reduced power mode. I've spent several hours on it, I've taken it to the dealership and...

    Camshaft & crankshaft position error codes plus stabilitrak and low power all at once

    We have a 2007 Yukon XL with a 5.3L engine. Recently, the check engine light came on (error codes P0341 for camshaft position sensor, P0335 for Crankshaft Position Sensor Circuit, and second P0335 for Crankshaft Position Sensor Circuit). A few days later, the Stabilitrak message came on followed...
