2001 Yamaha 150txrz oil issues

[Captkeith]

I'm now getting the correct icons.

[rodbolt17]

at key on engine off what does the oil visual indicate after it self tests?
not hard to believe it at all, even though a tag was attached to it when it came out of the box.

[Captkeith]

The pic shows the visual. Not sure if your able to see if well

[Captkeith]

Looks like showing full oil ?

[Captkeith]

I have to read up on these icons

here you go rod

[rodbolt17]

as long as nothing is blinking that is a good sign.

now go find your wire diagram.

trace the black red wire back down the harness to the ECU.
typically it is going to change from black/red to green/black in the harness splice.
unplug the ECU and test continuity from that ECU pin to the engine block.

the ECU pins are numbered and color coded wires.

[Captkeith]

Ok. Anything to the hole in the back of the ecu ? Nobody said anything about the pic I attached several posts back

[Captkeith]

So I'm getting a reading of 848 ohms with the meter set to continuity and volume on. ? Have no idea what that means

[Captkeith]

I did the 180 second test. No transfer. Lights on tach blinked and horn sounded.

thought I would help Rodbolt out again with the pic(he says he cannot open up the thumbnail pics)


and I agree it looks like a burn place.

OP When You place you meter leads together (checking the lead resistance)while set to the same setting as when you measured the ECU connection, what do you read on your meter?

also I would be reading in the ohm scale myself if trying to get ohm reading. pay attention to where the decimal point is on the readings.

[rodbolt17]

between the ECU harness pin and the engine block you should have less than 4 ohms,closer to 0 ohms actually.

if you look at your harnessdiagram trace both wires black and black red from the remote tank switch. you will find the black goes to a splice point and the black red goes to a splice point.
follow the black red to the ECU connector.

yes that burn mark looks bad.
but before I dropped the coin I would make sure all the signals are getting to the ECU.

[Captkeith]

I did Exactly as you said. The green/ black wire traces back from the splice at the side of the engine where the oil connector slpice changes wire colors. At the point where the green/black wire goes into the center connector on the ecu, when put the multi meter on it - I was getting a reading of about 850 when grounded to the block

Did you notice him talking about checking some different wires now just to make sure all are getting to the ECU?

Just purchased a replacement ecu. I'll have it in about a week. We'll see if that's the issue. Thanks for all the help. I'll let you know what happens.
