You'll have to remove it from the truck. Block one of the coolant ports. On the other, you'll have to attach a source of regulated compressed air. Lower the whole contraption into a bucket of water and turn up the air regulator to around 20 psi and then wait. A consistent stream of bubbles...

The gauge thing is probably thermostat. Make sure the hose under the recovery tank's cap is attached. Sometimes they fall off, into the recovery tank. This means the tank will fill but no coolant ever returns to the radiator. Either that or it blew the head gasket. Sent from my XT1585 using...

You're most likely experiencing low boost during a regen, or erroneous temp sensor readings. Low boost is often caused by the turbo. It doesn't really matter if the shaft is loose or tight, it just cannot ever bind. If it's spun by hand with a bit of side pressure on it and it binds, then...

Does the truck suffer from low power when the DPR graph hits three bars? Does the DPR graph ever jump from a couple of bars straight to five bars or higher? Sent from my XT1585 using EO Forums mobile app

I can't find the wear sensor installation in the book. Granted, I spent about 3 minutes looking. I did find them in the wiring diagrams. They're in a series circuit, so you can splice them together if they are worn through. Sent from my XT1585 using EO Forums mobile app

I don't know anything specific about the FL/Cummins combo. I am extremely familiar with the 2012 Hino though. The biggest problem with the Hino is the burner system. It can be temperamental. It's health is directly affected by fuel injector health. The burner also needs maintenance every...

I did some sleuthing. There is a TSB for P0420. Take it to a dealer and get the ecm reflashed. This is a known issue. Sent from my XT1585 using EO Forums mobile app

Read the last line for P2463. It doesn't explain p0420, which has several causes. Edit: Pic removed. Sent from my XT1585 using EO Forums mobile app

It kind of sounds like it's asking for a manual regen (I'm not as proficient with Isuzu). You'll have to park for about 15 minutes to accomplish this. If it won't manually regen, you'll have to get an actual diagnosis. There's a million ways that this can go wrong. Sent from my XT1585 using...

Yes and yes. The plug/wires that connect to the sensor.

The fuel level sensor probably died.

Mixing and matching different transmissions and engines is going to cause nearly unsolvable wiring headaches. Everything is computer controlled, and they all have to be programmed to play together nicely. You're going to spend more making this Frankenstein function than you would if you'd have...

I imagine the fuel level sensor is the culprit. If you unplug the sensor and jump the terminals at the harness connector, the gauge should swing to full. Sent from my XT1585 using EO Forums mobile app

You've got a simple wiring issue, most likely. Also, depending on what fuses you pull, you can definitely set the check engine light. Most rollbacks (I'm assuming it's a roll back) have PTO and beacon lighting attached directly to the batteries. I'd yank out both batteries and scrub every...

What year is the truck? How is this truck configured? Is the pto wired into the ecu, or is it just wired to a dash switch? How do you raise engine rpm? Sent from my XT1585 using EO Forums mobile app

There's base engine oil pressure, and injection oil pressure from the high pressure oil pump. I won't know which is which without that code. Sent from my XT1585 using EO Forums mobile app

I can't pull this one up. I assume it's because it's a Canadian truck. Sorry I can't help you there. You can give this to a Hino dealer near you and look at warranty history and if the have been recalls performed or of any are outstanding. Sent from my XT1585 using EO Forums mobile app
