Symptoms & Solutions

Oil consumption seems excessive with my motor. Is the ECU/EMM defective?

An ECU/EMM failure can not cause excessive oil consumption. The most likely causes of excessive oil use are - Oil lift pump failure, restriction (pinching) of the oil return line, oil injector failure.

Your usage cycle could also be a contributing factor. When the engine coolant temperature is below normal temperature, as the engine is accelerated above 2500 RPM, the oiling system delivers multiple injection shots. If this operational cycle is continually repeated, excessive oiling could be observed.

My motor experienced detonation damage to a cylinder. Is the ECU/EMM defective?

My motor seems to run rough at certain RPM ranges, particularly off-idle through 2500 RPM. I would like to have my ECU repaired. What should I do?

While performing a cylinder drop test, I noticed one or more cylinders did not respond properly. I believe the ECU/EMM is defective because the cylinder has great compression, spark, etc.

My motor idles too slowly. I think the idle governor is broken.

My ECU/EMM communicates with my laptop for about 10 seconds or so and then goes dead. What is wrong?

My ECU/EMM has been overheated and now the engine runs poorly. What has happened?

The repaired/replacement EMM doesn't function correctly. The symptoms are - the motor starts and dies, drops a cylinder when I accelerate, or idles poorly.

My engine is running a little rough. It seems lean on a cylinder. My friend told me he heard the fuel injector driver could be getting weak and I should have the EMM repaired.

I have a newer motor with an EMM. It keeps setting codes 38 and/or 39 (oiling system failures). I replaced the EMM and still have the same problem. I know the motor is getting oil. What's wrong?

I just don't understand ECU offset. What is going on?

loading...

Sometimes my motor revs up all by itself. I’ve done all the checks. I suspect my ECU/EMM is bad.

I keep getting TPS codes (12, 13, or 14). Where do I send my ECU/EMM?

Almost every time I go out, the codes for the air temp sensor malfunction are set. Is my ECU/EMM bad?
