What codes other than the P141F, and P2030. Am I correct in assuming you have a copy of DX2. Have you ever performed a 150k burner maint.? How many miles?

If your computer guy has DX2 dealer software, you can perform this. Tech tip and see if you have a restriction in the suction side of the system.

P0087 and P0088 codes are for fuel rail pressure. I would start there and verify no debris in tank, or the elbows at the fuel filter. Check for air in the fuel. We have seen lots of issues with the common rail pressure sensor connector wires giving erratic readings. How many miles/hours? Is...

Well you don’t see that often. Thanks for the reply.

Ok I got your vin and checked the coverage. I replied to the PM from flying-van. Oil cooler housings are covered under Base engine warranty from manufactures defects. The truck has base engine warranty for 3 years and unlimited miles. Good till 12-5-19 Unless someone hit it with a hammer or...

I don't have a crystal ball. For all I know a metric left-handed dingle arm hit it while going down the road. We can go back an forth on what may have caused it..... or you could send me your vin and I can check and see if a oil cooler is covered under the Hino 5 year 250,000 mile warranty. Your...

I have never heard or seen a oil filter housing crack EVER. Been working on J08 Hino engines for 14 years. Pm me the VIN. You should have coverage on a vehicle this new. Ill check your warranty certificate. I have seen many camshaft housing gasket fail and leak oil down he rh side of the block...

95% it is a brake switch issue. If you have someone watch your brake lights, press down lightly on your pedal and see if you can get the brake lights to stay on. It may take several times. If they ever stay on without the pedal depressed. Your switch is out of adjustment. There is an updated...

Same piece, valve and DC motor. don’t waste your time with aftermarket, buy OEM and get the warranty IMHO.

Check the wires in the pass through. The VNT and the EGR share power and ground. I would load test the power. & ground with a test headlamp and verify proper can voltages. I have seen a few Egr valves fail but it seems to me like they are certainly missing something.

I have seen stuff get sucked into the hvac duct work if the cabin air filter in the cab comes loose of is missing. I found a plastic bag restricting the duct. Try fresh air and recirculated air and determine if one flows better than the other. And yes check the external air inlet duct under the...

Ignition coil not ign can. Stupid autocorrect

P2463 in my experience is a faulty atomizer. Is your atomizer leaking fuel externally? It is the black box next to the ign can for the igniter wires. Just changed one yesterday $1800. 2.5 hr labor. Any other codes?

load test wires with a headlamp. You can perform a wire overlay. Check the pass through connectors for green pins. No communication could be datalink, power or ground. Load test the power and ground and check resistance at the TCM. Let us know what you find.

You are not getting commanded gear signal from the transmission control module. Last time this happened I had to replace the TCM. I have also seen corrosion in the pass through cause this. Best bet is to install a known good one and see if your issue goes away. 4 bolts and it comes right out. Do...

Strange that it did not have communication or a p0045 codes. I would check the intake throttle valve. I just had one act up on a UD this week. it would take you less than 2 min to remove the CAC hose, grab the shaft and wiggle it. The one I replaced was only $162. Make sure the key is off FYI.

Year? codes? what transmission? Check transmission light on? check engine light (yes/no)? recent repairs? These are the kinds of things that you should include when asking a question. Like anything else in life, you get out of it what you put into it. With more details I may be able to help...

What codes? If the DPR is smoking it is breached and will need to be replaced. The DPR itself is not your problem, its upstream of the DPR 70 % injector failure, 20% exhaust brake adjustment issue and 10% Burner/Mantle/Atomizer issues. Codes and any injector or exhaust brake history would help...

p2033= High DPR outlet temp p0546= High DPR inlet temp P2002 DPR malfunction =high soot load P2101 Intake throttle valve sticking P2103 intake throttle valve high input. Sounds like you have a sticking intake throttle valve, possible worn butterfly shaft or possibly a wiring issue. Remove the...
