need code interpretation help
 

No CEL, but I pulled codes today (airbag light was on after wife adjusted seat...I can deal with that)

17748 - Camshaft Position Sensor (G40) / Engine Speed Sensor (G28): Incor. Correlation
P1340 - 35-10 - - - Intermittent

17536 - Fuel Trim; Bank 1 (Mult): System too Lean
P1128 - 35-10 - - - Intermittent

I cleared codes to see what comes back...I'll run tests on 17536
About 2 months ago, I had a CEL and 17536/P1128 code - replaced MAF, showed normal readings and CEL never came back.

Any thoughts on 17748?

17748/P1340/004928 - Camshaft Position Sensor (G40) / Engine Speed Sensor

(G28): Incor. Correlation
Possible Causes
Timing Belt/Chain incorrectly installed
Timing Chain probably lengthened
Camshaft Position Sensor (G40) faulty
Engine Speed Sensor (G28) faulty
Possible Solutions
Check Timing Belt/Chain installation
Use Measuring Value Blocks (MVB) to Check Timing Chain
Check/Replace Camshaft Position Sensor (G40)
Check/Replace Engine Speed Sensor (G28)

Timing belt was done @2 years ago...how do I use MVB to check timing belt?

Now I'm thinking that these may be residual codes
 

I looked at my last set of codes @3 months ago when I replaced the MAF. I had the same exact 2 codes (but with a CEL).

I don't think I have pulled codes since then.

Wonder if these two were just lingering around.

"Intermittent" in this context means the conditions that set the stored DTCs ...
 

did not exist at the time the DTC memory was scanned/cleared.
