C3 Picasso 1.6 120 VTi Misfire

Post by PicassoFan »

Hi everyone. I have been battling with my Picasso for a while now. It came up with the "anti-pollution filter" warning. It started to misfire as well. I ran the diagnostic, and it came up with error P1338. I replaced all plugs and coil packs 1 and 2. I changed both camshaft positioning sensors as well. Still no change. I then took a multi meter and, with the ignition in the ON position, got the following OHM readings: Cyl 1 = 36, Cyl 2 = 34, Cyl 3 and 4 were in the 70's. The multi meter beeped on Cyl 1 and 2. I took the reading as follow: Removed the connector from the coil pack and read the current on the electrical plug (3 pin female).
Now from what I read, the P1338 error means Cyl no 2 is not firing correctly. Any suggestions? Thank you in advance.
