Hello everyone,
I have Corolla GLI 1.6 model 2011 automatic. Its been a while the car burn out the ignition coils. It has burned the coil 4 time in last 6 months. Purchased kabli the set that costs 10K.

Anyone have any idea what would be reason for this and how it can be resolved.

Thanks for your help.

Scan the car first!

[pwuser157649433979]

Nothing comes up on scanning. No check light untill it start shivering.

Check if your car reduces oil?

Something else is wrong which is causing this. I had my gli 2nz driven upto 250k kms and no coil was changed or whatsoever just regular oil changes and plugs etc.

[pwuser157649433979]

I regularly check the oil. After 5k km it hardly reduce 3 or 4 mm on stick.

[pwuser157649433979]

Yes, thats is what i am looking for.

before you change the coils check for any fractures in the wiring. insulate the coil cables with PVC heat shrink tubes. check the coil connectors with multimeter for any arc leakage. coil go bad when constant ignition current leakge is happening.

Make sure ur not washing the cars engine area at all.

Another that could be happening is that, Some mice might have eaten wires connecting the ignition coils which might be causing the short circuit.

the biggest reason for burning coils is worn out spark plugs and also a bad engine ground.

What is engine ground and how can it be bad??

Bolay to

May be some parfarmans plug is installed.

Do you know any good electrician in islamabad/rawalpindi who can diagnose the actual issue. ?

[Xulfiqar]

Your issue is with you washing the engine.

[pwuser157649433979]

No, i don't get engine washed. Sometime i ask the cleaner to dust off with air.

for me to help you, please tell me if you do work on your own or ask mechanic for it? do you own oscilloscope? do you own a DMM? and are you aware of testing for for voltage drop? Are you aware for testing AC current ripple in system?
