The engine stalled as I was idling and preparing to back out of the garage. The Innova 3160 stored a Diagnostic Trouble Code (DTC) and Freeze Frame Data. I am am still not confident in my ability with the Innova, so let me provide the DTC screen content to you:

P0340. Chevrolet Stored

*CMP (Hall) sensor signal circuit is open or shorted to ground.
*CMP (Hall) sensor ground circuit is open.
*CMP sensor power circuit is open (test power from MFI relay)
*CMP sensor is damaged or has failed.
PCM has failed (PCM provides a VREF signal to sensor)
P0340 (1/1) stored
Intake Camshaft Position Sensor Circuit
Severity 2 of 3
Repair immediately if drivability issues are present. Threat to essential system present. Threat to essential system components if not repaired as soon as possible.

Freeze Frame:

Fuel: OL
MAP: 30 (inHg)
Eng RPM: 0
Veh Speed: 0
ECT: 70 degrees
STFT B1: 0.0%
LTFT B1: -3.9%

Also note that the "CAT" icon has turned from green to red and is blinking.

Please recall that I previously noted the CMP was covered with grime and oil from previously a repaired leak (I have corrected all oil and fluid leaks). The car ran a little better after I cleaned the cable connected and ground connection of the Camshaft Position Senor.

What are next steps?

Thanks for all you help.
