Hello my name is ***** ***** I will be assisting you with all of your vehicle questions today. Give me one moment while I review your question and come back with a answer. Please be aware I do not know your skill level or abilities so I will be asking a lot of questions and in a lot of cases we will respond to each other quite a lot before we find a solution. As far as phone calls are concerned that is the system prompting you, not me, and they do cost more money, I prefer text but in some cases a phone call is required.

Is it possible that the ECM is bad? How can we test it?
Auto Mechanic: Mechanic01, ASE Certified Technician replied 4 months ago

That is possible, but before we check all of that, are you getting any return codes after the sensor install?

1. Manually ground the Oil Control Solenoids for bank 1 and 2, then compare the amount of change that each cam can make. Ground the White wire for bank 1, Green for bank 2. If they both change the same amount, the intake cam gears are mechanically moving full range. Expect about 60° of change.

2. Check engine compression side to side. If the compression is the same, it is likely that the engine is in time correctly.

3. Check the intake cam gear teeth for the CMP sensor, compare against a known good picture. These teeth are pressed into the gear and tend to move retarded over time. It seems like they stop at -18° usually.
