I have an error code of P0352 in my car, and my question is which coil is B? The car is a four cylinder, and I just do not know if B is the second coil from the left or the second from the right when standing in front of the car?

I have already wasted about three hours on google images and YouTube trying to figure this out, and sadly, I am still stumped.

Please help!

Coil B is the number two cylinder. Second from the front or crank pulley. From left to right is a, b, c, d or 1, 2, 3, 4. B is second from left. Please let us know if you need anything else to get the problem fixed.

My 2006 corrolla is showing a code of P0353 "Ignition coil C Primary/Secondary circuit. Will replacing the coil take care of this error code?

Check wiring first, this engine uses individual coils. Buy one, replace coils one at a time until code goes away. It would be best to have code reset prior to testing.

Ignition coil receives its power supply from the Ignition switch when in ON or START position.

If power is not available, the EFI relay and Circuit Opening Relay would not work.

At ignition coil terminal # 1, ( Black/White wire), apply battery voltage to test if vehicle can be started.

My daughter has a persistant CEL on for over a year, the code that has been registered at 4 different places (including at a Toyota dealer) is PO300 random misfire and mis-fire PO302. I also asked my personal very good mechanic what this could be since the car seems to mis constantly, especially when you put the car in gear. The tranny has been check out thoughly at a transmission shop by running a code check on the PCM. My mechanic is almost certain that it is a coil, I saw all 4 of them on ebay for under $100. My question is will replacing all 4 coils solve the problem

Other wise the car seems to run and drive OK

There's a better way to diagnose this than by replacing parts. Code 302 means cylinder 2 is misfiring. If the car is due for new spark plugs, change them first, then swap the ignition coils between cylinders 2 and 3, and the injectors between cylinders 2 and 4. Erase the fault codes, then see which cylinder sets the next misfire code. If it's still cylinder 2, suspect a valve or compression problem. If the misfire moves to cylinder 3, suspect that ignition coil.

Shakes or Wobbles problem
2001 Toyota Corolla 4 cyl Two Wheel Drive Automatic

I believe that it is the coil to one of my cylinders(the 1st?). My car shakes as I begin to accelerate from a starting point. If I accelerate slowly, it picks up fine, but a lot slower. If I accelerate at a normal start, my car shakes badly. Is it my coil, could I need a tune up?

You should be getting a check engine light if a cylinder is misfiring. I would check the plug first for fouling/gas soaked.
If you have a check engine light, get the PCM scanned at a auto parts store (free).

Hello,

Here is a great guide on how to test your ignition coil, This is for a multi coil system but it will work just fine for your car.

https://www.2carpros.com/articles/how-to-test-an-ignition-system

Inspect Primary Coil Resistance
Using an ohmmeter, measure the resistance between positive (+) and negative (-) terminals.
Primary coil resistance (Cold): 1.1 - 1.7 ohms

If the resistance is not as specified, replace the ignition coil.

Inspect Secondary Coil Resistance
Using an ohmmeter, measure the resistance between the positive (+) and high-tension terminals.
Secondary coil resistance (Cold): 9 - 15 k ohms

If the resistance is not as specified, replace the ignition coil. diagram (below)

Please let us know what happens.

Cheers, Ken
