Cel Questions

[chubert]

I am researching some trouble codes and need some help.

A couple weeks ago I got a "Pending" P1530 code but no CEL light. Just last week the light lit up and when I scanned it it had a "P1539" The 1530 was gone…. What confuses me is these are "Cam Adjustmnet" errors which seem to typically be a solenoid or actuator but the two codes are on two separate banks?? Is there something in common that would post both codes?

It seems to run an idle fine. I have owned to for about 1700 miles without issue so far...

The car is a 99 2.5 Boxster with 53K.

Intermediate shaft bearing failures are sometimes predicted by deviations in the camshaft timing like you've seen here. I'm not saying that your IMS bearing is about to dissolve, but it's one thing to be looking at. Take a closer look at your camshaft deviation while the car is running, and see if there are some problems left / right there. Since the bearing affects both camshafts equally (mostly equally), it's not uncommon to see separate left/right codes in this situation.

Interesting thoughts. Until I got the 1539 I was just assuming I needed to change the Solenoid or actuator on Bank 1 due to the 1130 code. Now I am not sure. I reset the P1159 and it showed "pending" again about 7 miles later but the light has not come back on yet. I reset it again and I will see how it behaves ont he ride home.

How would I check my camshaft deviation when the car is running?

I do have a bit of clatter when starting it cold. but is goes away after 2 seconds or so. Could the plasitc chain guides be worn?

Thanks

Update : I am back to thinking it's an actuator or Solenoid. I thought the first code was a P1530 but it really was a 1524. They are both on Bank 2. I think this is a good thing!!!

I'll run it for a few more cycles and see if anyting else pops up.

That's generally not a good sign, there is something wrong in there...
