I have a Peugeot 208 1.0 2013. Theres a code that keeps coming up, p1336. I have changed the spark plugs twice and replaced all coils and the issue is still there. I've been told the timing belt needs changing but also been told that would not cause misfire issues as its not related to combustion. Anyone else had this issue? The car feels so unsafe to drive at times as it keeps entering limp mode for a short period when accelerating in 2nd or 3rd gear in low revs. I've had it in a numerous garages, including Peugeot and no-one can tell me the issue.

Peugeot 208 Fault Code P1336
Meaning Random/multiple cylinder misfire detected

Possible causes
(1) Oxygen Sensor in front of the Catalytic Convertor
(2) Hall/MRE Sensor on the inlet camshaft.
(3) Hall/MRE Sensor on the crankshaft.
(4) Injectors 1 through to 4
(5) Ignition Coil 1 through to 3
(6) Knock Sensor.

Are you capable of running tests with a multimeter to determine if the above is the cause ?

 

[jonathanh]

if you have eliminated coil pack and spark plug then it is either

a) weak power supply to the coil pack (unlikely) delivering a weak spark

b) fuel issue - failing injector

c) compression issue

i would do a compression test for c) and for b) swap the injector between cylinders

I'd be able to if I knew how to test and where the locations are of the above.

What code reader is giving you the P code?

If all the above test out correctly, then you have a mechanical issue, which a wet and dry compression test should identify. This also assumes the code given is correct.

Hope you find this helpful.

Nor sure as it was a garage. I'm not a mech so wouldn't have a clue.

That's some very useful info so thank you for that. I will have to give it a go.

Would it be possible that a clogged or failed catalytic converter could cause the issue? I seem to be hearing a blowing from the exhaust (potentially unrelated to the cat) at the same time as the the drop in acceleration then all of a sudden the power will kick in and 'zoom' off if that makes sense. 🙃

Is it possible that the gap in the spark plug(s) is to far?

Thanks again btw!

Should have a different code.

 

[jonathanh]

Spark plugs are pre gapped so should be right. Did you check the gap anyway when fitting?

 

[Smiley346]

Should have a different code.

I only ask as since having the 2nd set of spark plugs in, the hesitation on acceleration is still there slightly but not all the time. There's an overall improvement in the feel of the car when accelerating in 2nd/3rd gear but no longer getting the engine management light coming on. 🤷‍♀️

I didn't fit them myself, I had a mechanic do it so I'm guessing not

Look for air leak after the mass air flow meter, dipstick has o-ring on it, can be a source of un-metered air into the system if the seal is weak. Would not take much of a leak to cause 1.0l engine hesitation issues.
