Direct injectors spray into the combustion chamber and sit in the heads. Port injector s spray into the manifold right before the intake valves

Hi, I have a Lexus Ls 460 with the exact same problem, I get the same error. I've swapped the injectors, checked wiring, swapped spark plugs and ignition coils, but the injector 4 error remains... I've done everything possible, what's the outcome of your lexus? thanks anyway!

Hi

Did you ever fixed your problem on the fuel injector open circuit? I jus got the same issue, swapped coils, injectors, checked the harness. Motor runs rough , check engine is one with warning to check my VSC system. Codes read P0204 and P0304.
there was no warning and it just came on one morning. I know I’m going to get reamed at the Lexus dealership.

The coils and the injectors did you buy them oem or chinese aftermarket? If you bought aftermarket, honestly I would reinstall the old stuff. Take it to a good mechanic, no need to take it to a dealer, a good mechanic (who specializes in toyota/lexus) with a scan tool should be able to solve it.

hello, yes i managed to solve the problem. I thought there were 8 fuel injectors (low pressure) present but there are 16... the first 8 that are visibly mounted are cold start injectors and the other 8 (high pressure) are mounted under the inlet collector. I saw rats biting the wiring of the fourth fuel injector below the intake collector.

I only see one row of fuel injectors on each side of the intake. Where are the other 8 located? Are they under the intake? Does anyone has any diagrams on this?
