2000 toyota echo ignition coil specifications

Hi Everyone,

I have a 2000 Toyota Echo. The check engine light comes on freguently. Replaced the 02 sensor, cleaned MAF sensor, tuned it up…the check engine light stayed off for 3 months, but it’s back on again. Now, we are on to the coils…What is the proper resistance rating for ignition coil? We have an Echo repair manual, but this information is not in there.

By the way, driving this morning…the check engine light went off!


What needs to be done at this point is have the codes pulled rather than throw parts at it.
Drop by a local AutoZone, Advance, Checkers, etc. and they will do this for you free. Post any results back here for discussion.

Sorry, should have mentioned the codes.
P300, and P302 are the codes that came up.

What repair manual do you have? the Haynes manual usually has that info at the beginning of the chapter in specification.

I have the manual from Toyota. Not the little manual that comes with the car. This thing’s as big as a phone book.

So does the shop manual translate the codes or do you need a second “emissions” manual for that…

What to the codes say is wrong?

First off I commend you for having the factory service manual for the car. It is one of the best investments you can make in the car.

The codes you gave are for a general misfire and for a #2 misfire. Have you tried changing the plugs yet?

Yes, changed the plugs about 3 months ago. New 02 sensor and cleaned MAF sensor at the same time.
When the light came on again recently, we figured it might be a coil problem.
But we can’t find the resistance rating in the Toyota manual…or anywhere else for that matter.

Isn’t there anyone out there with any suggestions?

Did the trouble start before you changed the plugs or after? What kind of plugs did you put in? Toyotas are notoriously fussy about non-OEM plugs.

Ohm them all out, and take note of any with a big deviation in resistance from the others.
