am I following the troubleshooting guide correctly?

So my gas mileage sucks on my truck, when i'm on the freeway the trany isn't always locked in. I know the lock up solenoid isn't bad, it was replaced 2 weeks ago. I checked the brake signal switch. Its good.

So according to this chart (in the pic) If there is voltage between L4 and E1 at the computer, while in Hi-2 and the key switched to on then I need to test/adjust the TPS?

Just making sure because the TPS is a p.in.the.a to test and I will just take the throttle body off and put a new gasket on if this is the case.
