Need4Speed Posted November 12, 2010 Share Posted November 12, 2010 I've got three coil-packs, one virtually brand new - less than 500 miles - and two old ones which according to my measurements are fine. £60 delivered. To clarify, there are only 3 coil-packs, not 3 pairs. SOLD Link to comment Share on other sites More sharing options...

little num Posted November 20, 2010 Share Posted November 20, 2010 when you say seem fine according to your reading's how do you read them to see if they are perfect working order. Link to comment Share on other sites More sharing options...

Dnk Posted November 20, 2010 Share Posted November 20, 2010 when you say seem fine according to your reading's how do you read them to see if they are perfect working order. I'd like to know this also, then i'll check the 6 uk coil packs ive got and sell them too Link to comment Share on other sites More sharing options...

Need4Speed Posted November 20, 2010 Author Share Posted November 20, 2010 Toyota specify a range for the primary winding resistance of a coil-pack, hot and cold. That's why I only have 3 for sale: 2 were out of range and one was cracked - hence an intermittent missfire. Link to comment Share on other sites More sharing options...
Dnk Posted November 20, 2010 Share Posted November 20, 2010 What is the resistance figures ? Link to comment Share on other sites More sharing options...
Need4Speed Posted November 20, 2010 Author Share Posted November 20, 2010 Hot: 0.68 to 0.98 ohms (+50ºC to +100ºC) Cold: 0.54 to 0.84 ohms (-10ºC to +50ºC) Link to comment Share on other sites More sharing options...
Dnk Posted November 20, 2010 Share Posted November 20, 2010 Thanks, i'll make a note of those and check the spare set i've got Link to comment Share on other sites More sharing options...
jagman Posted November 20, 2010 Share Posted November 20, 2010 Those are coil resistances and not the most important thing , what you need to know is the insulation resistance in megohms , but as with most things electrical , few actually know what you are talking about if you quote these numbers . If the insulation resistance is low , then the coil resistance is academic as the coil pack is shot. Link to comment Share on other sites More sharing options...
Need4Speed Posted November 20, 2010 Author Share Posted November 20, 2010 I'm simply quoting the Toyota service manual. Yes, it's what makes it to the plug that counts. Link to comment Share on other sites More sharing options...

Would you care to elaborate, can this insulation resistance be checked and if so how, also is there a guide to what the figures should be ?
