Dear All,

I'm a little bi confued while searching the internet.

I need to repleace three iginition coils on cylinders 1,2 and 3, but i have no idea which ones are those.

Can You help me with identification on cylinder numbering ?

Thanks in advance
Lukasz from Poland

Edit:
Or maybe there is another problem, i have such code errors:

P0134
P0154
P0300
P0301
P0302
P0303

Any help ?

 

Here ya go :

 

Thank You very much that will hepl me.

Do Yu think that it is possible that 3 coils on one side of engine could fail ?

or maybe it is problem with Camshaft Sensor ?

Best Regards
Łukasz

 

Unlikely that 3 coil packs fail at once.
1. Crankshaft sensor.
2. Camshaft sensor.
3. PTCM ( PCM )

Fuse 11 supplies power to all 6 coil packs, see diagram

 

So i guess there was no need for me to buy 3 ignition coils :/

there is one more info:

engine cuts off those cylinders only when ts hot, on cold everything seams to be fine.

Shall i change those coils or shall i buy and replace both sensors first ?

Best Regards
Luaksz

Edit: Camshaft/Crankshaft sensor failure should give any error i guess ?

 

Have you checked the spark plugs on the cylinders in question?

Also, if you have access to a borescope, I would have a peak inside while the plugs are out.

Does the car smoke at all?

 

Sounding more and more like an intermittent wiring fault.
You can eliminate the defective coil question by swapping all 3 coil packs from 1,2,3 to 4,5,6.

Often, crankshaft / camshaft sensor being defective does not store any error codes.

 

Those were changed about 6-7 months ago, i bought high quality so i don't think that something is wrong with them, especially as the issue is on whole left side of engine (

Ok, I will replace those 3 coils with new ones - less work and let You know if it helped.

I will also read the error codes after replacement and post them here

Thanks a lot for all information's.

Best regards
Łukasz

 

Car is able to ride, there is no blue or black smoke, I do not have the access to borescope.

Thanks
Łukasz

 

I know someone that just had this problem and his 02 sensor for that bank went out.

 

Good catch Josh !

 

Yeah it had me and him scratching our heads to the point of skinning our brains. lol

What are the other codes: P0134, and P0154?

 

So it can be caused by O2 sensor ?

My errors:
P0134 - Oxygen 02 Sensor Circuit No Activity Detected (Bank I Sensor 1)
P0154 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)
P0300 Random/Multiple Cylinder Misfire Detected
P0301 Cylinder 1 One Misfire Detected
P0302 Cylinder 2 Two Misfire Detected
P0303 Cylinder 3 Three Misfire Detected

 

Description of vehicle trouble code P0134 - Oxygen 02 Sensor Circuit No Activity Detected (Bank I Sensor 1)
P0154 02 Sensor Circuit No Activity Detected (Bank 2 Sensor 1)

So we have O2 sensor codes on BOTH banks ?
Could it be setting these at startup with a faulty air injection pump / circuit ?

 

Both 02 errors occurred over an year ago (my mother is a car user and she just told me that :/ )

 

Yes, very much so. The O2 is very important for A/F.

I think it would throw the P0410. It may have been a slightly bad O2 on bank 2 but a completely shot one on bank 1 for every cylinder to missfire.

Was anything done because of them?

 

One thing to try is to take where the O2 sensors plug into the black connectors and switch them. See if you missfire on 4, 5, and 6.

EDIT: Or missfire on all cylinders, because at that point the ECU is determining A/F for the wrong banks.

 

I'm not sure where shall I seek for o2 sensors

 

They go into the exhaust manifolds. Near the rear of the engine bay. The black plugs are right on the firewall I think (not sure, because mine are different).
