The transmission control module is responsible for correct shifting of is on side of tranny. the throttle position sensor takes all the necessary measurements and sends it over to the Electronic Control Module on transmission to make it shift, if its ok!

Always use the OEM oil filters they are always the best, and just check your oil recommendations in the service manual.

But you can use a fully synthetic oil which is the best grade off oil to use.

There are Three things that cause this code other than vacuum lines and hoses, the fuel tank pressure sensor, monitors the pressure in the fuel tank and times the vacuum decay, The canister purge valve and the canister close valve, these are all maid to be tested with a scanner but you can Do this, locate the charcoal canister and find the valves have someone turn the switch on while you feel and listen for a click. You can also check with an ohmmeter just check for continuity. If the fuel tank is rusty on top there could be a pin hole in it. I hope this helps. Take care.

what i heard that it is like removing it from under the car which is not possible without lifting the 4 wheels. Also you may want to first do this before removing the alternator, even the multimeter shows the alternator failed test. Simply go underneath the car to check for the wire that comes out from the alternator and goes to the battery to charge it up. This particular wire that is coming out from the alternator to charge up the battery is completely fused or burnt.
