2019 EZGO oil pressure light troubleshooting
2019 EZGO Express S4, Kawasaki with a carb, not EFI.
I've done a lot of searching and can't seem to find an answer on this. This cart is brand new, not even the first tank of gas through it. The low oil pressure indicator is staying illuminated. Perfect oil level, no power loss, no funny noises, etc. First thing I did was change the break in oil and filter per EZGO, there was around 8 hours on it. When I removed the wire from the sending unit the light goes off. I took a volt meter and tested the resistance with the engine off - 0 ohms. With the engine running, the ohms jumped all around, so infinity i guess? The switch is a normally closed switch, so once it builds oil pressure it should go out. By testing the resistance with the engine running, i think its operating as it should, but the light in the dash is staying on. I've traced the wire to see if its grounded anywhere, but everything looks good. Is there anything else I should try? It looks like I would have to remove the engine to change the sending unit, it looks almost impossible to get a wrench in there. I'm not convinced the sending unit is faulty. I'm sure this is covered under warranty, but the dealer is a 2.5 hour round trip, that I would have to make over the weekend during deer season |

I've run into the same issue with my cart. I'll be following this thread to see what's the resolution.

Is yours a newer Kawasaki?

I would be making that 2.5 hour trip. If you start messing with they are going to blame you if something happens. Just my 2 cents

If you remove the sender wire at the switch with the cart running and the light goes out, bad switch or very low pressure.

Re: 2019 EZGO oil pressure light troubleshooting
The light goes out with the wire removed. It’s brand new, I hope there isn’t any oil pressure issues. No weird noises, or knocking. I bought the new oil switch, but not sure how to get a wrench to it. It’s blocked pretty good by the motor mount skid plate.
Thanks for all the replies. May carry it over to the dealer and see what they say. |

With the new switch and oil pressure gauge, I still have the same problem. There is zero oil pressure. I've ordered a new oil pump and I'll be replacing it as soon as it comes in. If that doesn't fix it, I don't know what to try next.

That’s not good. Is your engine a Robin?
