Daihatsu ESSE Error code P1300

[mbaqurashi]

Dear All, few months ago my car start showing check engine light for a while. after scanning, i found its P1300 error code which translate to cylinder 1 ignition failure. i exchange its "pencil like" ignition coil with cylinder two. but still that error P1300 pop up.

In rainy days (little bit cold days) check engine light appear rarely. but in hot summer days check engine light appear very often and stays on until engine running.

my doubts are that wires connecting to ignition coil 1 are broken / short circuiting, but i don't know how to check them. i need your expert opinions to help fix this P1300 error.

P1300 on multicoil toyota pertains to missing IGF (ignition feedback) signal from cyl1 to ecu.

Check the wiring, igf wires are shared common by all cylinders as the ecu can time the cylinders from the IGT triggers it sends to the coils.

Any sensible person who understands toyota ecu wiring can test this. If in Lahore contact @syncview
