Troubles with OBD II - HURRY
I am having a code P0302 from the OBD II system, this means that there is
trouble with the #2 plug. The car runs like it is miss firing, it kind of pops and sputters like a valve. Trusting OBD II as I do, I tested the plug wires, and the #2 wire seems to be open. The #1, 3, and 4 have resistance readings as follows, 10.0, 7.6, and 5.5 k ohms respectively. If the resistance is a function of the length and the #1 is double the length of #4, then the resistance readings are in line. I would expect #2 to fall in between 1 & 3, or about 9. Before I go out and buy new wires, is my test valid? |
Re: Troubles with OBD II - HURRY
If you are reading a straight open that is all you need regardless of what a
particular resistance reading is on other wires. Could it be just a plug, change the plugs. -- Coasty SEMPAR PARATUS (ALWAYS READY) Remove The SPOOGE To Reply "Jeff Strickland" <crwlr@yahoo.com> wrote in message news:g_-dneOfd5_UDF3fRVn-gA@ez2.net... >I am having a code P0302 from the OBD II system, this means that there is >trouble with the #2 plug.

Re: Troubles with OBD II - HURRY
Your test is fine Jeff, I'd suspect a connector has come off where it
connects to the carbon fiber conductor. I'd install another set of OE plug wires, most wires sold by Autozone etc. are pretty crappy quality. Especially avoid those advertising "low resistance" which will introduce electrical noise into your CB and AM radio.

Re: Troubles with OBD II - HURRY
Plugs are OK, I think. My brother in law replaced them two weeks ago because
the engine was miss firing. The boneheads at AutoZone told him that if the Check light was off, there were no codes to gather, so we couldn't see if we were even working on the right stuff. I'm off to the store to get a new set of wires. This is one of those projects where the expensive ones are the right ones, isn't it?
