DIAGRAM FOR 1999 ACURA TL TRANSMISSION SOLNIOD CODE P0740

SOURCE: Check Engine light on Acura TL 3.2 1999

You can turn off the Check Engine light by either disconnecting the battery or by using a code reader to clear the codes. However, if the problem still exists it will come right back on. Instead you should get the code read, find out what the problem is, and fix it. Your local autozone or checker auto parts store will read them for free.

Hi,

you need a 6 inch extension, short 3/8 ratchet, 5/8 plug socket, 3/8 swivel "u" joint, (sold at sears) 8mm 1/4 drive socket deep well and 1/4 inch ratchet.

find the coil packs (6 total, three in each head.)
remove the two retaining nuts holding each coil pack using 1/4 8mm socket and ratchet.
twist the pack to break the sticking boot below.
pull up (be careful to not rip the boots however it may still happen but rare.)
remove coil packs, the rear is a little more difficult with the intake.
use 6" extension and u joint and ratchet to remove plugs and replace.
reverse order to assemble. Good luck, and hoped this helped.

there should be a belt diagram from a label either on underside of hood or on radiator support. That should help if you can do it yourself.

SOURCE: ACURA TL SERVICE DUE SOON B1

It's a service interval reminder light that you should take your car to acura and have them perform the "b1" service. I would ask for an estimate first, and ask what that service includes. You may be surprised to find necessary and unecessary services. Some people view the b1 light as a way for Acura to get you car in there, quite possibly be charged for things you could probably do yourself.
