[s-cars] Cleaned G28 RPM Sensor, now a 2113 code

[Jim Fleischer]

Okay, so I cleaned the RPM/Engine Speed Sensor, boost came on quickly and then shut down again, and after a few times the CEL came on and it went into limp mode and stalled.  Happened yesterday with a stock ECU with Dawson after we cleaned out the cats.  Started right up again, pulled codes and got 2113.  From the SJM website:

2113 (Blink Fault Code), 00515 VAG1551/2 Fault Code Number 
(G40) Hall sensor in distributor 
(3B, early AAN engines) or camshaft position Hall Effect sensor later S4/S6 AAN engine). 
Distributor alignment, faulty sender, Mis-located sensor & distributor, Cam timing possibly incorrect on AAN engine, Check lower Crankshaft Gear keyway
Symptom: Engine will not start, power loss, check engine light may come on during driving above certain RPM

I replaced the CPS about 9 months ago, second one in a few years. I'm happy to do it again if need be.

BTW, I've cleaned the MAF sensor and connectors within the past couple of months.  No boost hose leaks, as I've pressure tested frequently the past month or so. Thanks for the suggestion Chris.

Further thoughts?

Thanks!
