p1337 Code on cold starts

[Daiced]

Here are the results of the obd scanner. Does this help my case ?

[Daiced]

I've recorded how the issue presents itself if that help.

Although weirdly enough i got another code this time which i've never gotten before which was the p1336.

P1336 is pointing to the crank sensor

P1337 seems to point to coil pack #1 (hence my question about type of plugs!

it MIGHT also be due to the timing being out ... have you tried googling p1137 Peugeot?

[Daiced]

The timing belt has been changed a year ago. But i've been thinking about the coil pack for a long time now. Is there anyway to test the pack? I do feel that the car don't have the 110hp that it's supposed to have.

[gazza82]

There probably is but I don't know how. (It was so mush easier with single coils and HT leads!)

In UK the test is usually to fit another known-working one. I'd also suggest pulling a plug and checking the make.

If you are down on power that could also be the timing is out .. one tooth will be enough!

[Daiced]

Well when the mechanic switched the timing belt he said that it had been wrong by two teeth, but it's a well known shop so i'm confident in the fact that the job was done right this time.

I'll have to take a look at those plugs when i get the time for it.

Back to basics. If you can get live data from your code reader. Immediately from a cold start, look at the fuel trim, IAT and coolant temp. and let us know readings versus ambient air temp. I suspect it may be a little lean on start up.

Does the readings tell you anything about the possible cause?

[Capncol]

Yes but you need to compare with ambient. You have told me what the ECU sees. Take the 3rd pic for example. If engine has been running for 20 mins and outside air temp (if car was outside) was 12 deg, then those readings are all over the place

Ambient temp was 0-1 celsius and those pictures are taken over the course of 10 minutes

They look ok except for initial fuel trim. Can you repeat test and check both O2 readings and post They should be fluctuating so can you give max and min fings and whether OL or CL operation?

[Daiced]

The thing i don't get is why the fuel trim goes to zero when the car is having the problem. As well as why the fuel trim always is negative before the issue occurs but turns positive after the restart.

I'll take a look at the readings tomorrow and report back

[Capncol]

This is why I've asked you to look at O2 readings

Okay, now i have 2 days left before i leave to my hometown where the weather is better so tomorrow i can do the test you asked for, but i don't quite understand what you meant.

Which O2 readings are you referring to?

[Daiced]

This is how it looks on the throttle app during start up vs after the restart

Oh and btw I have changed the sensor without any difference

[Capncol]

Both O2 (lambda) readings (sometimes listed as S1B1 & S2B1)
