There is a fault code P0352 – ignition coil B, primary/secondary circuit malfunction.
Solution (what I did for reference)
P0352 is #2 ignition coil while P0351 is #1, P0353 is #3, P0354 is #4.
(From left to right, starting from belt side then 1, 2, 3 and 4)
- Remove engine cover;
- Remove clips & nuts(10mm) holding the coil;
- Pull up & replace bad one with good coil;
- Reconnect clip to coil with a “click” sound;
- Put back all nuts & engine cover.
Let’s restart engine to check if the warning light was still on.
Alright! Check engine light has gone.
