It has true duals and a leveling kit. When I bought the truck it was a mile trip home that I took it on. It had absolutely no problem except for the engine light was on which I figured was just because of the true dual exhaust. It drove good for a week and now I am having a multitude of error codes showing up when scanned and problems being caused.

It shuts my motor down to a rough idle. I have to pull over turn the key off for 10 seconds then I can turn it back on and its okay. I am also having an issue with when I have a passenger get in it turns on my brake light as well as my abs light and states that I need to service the brake system. Now just yesterday it is giving me another code and reading saying that I need to service the four wheel drive.
U1096 Engine Fault Code
The truck has been in what seems to be a low speed front end collision as it new front fenders, the bumper was bent and a few other things im sure.
The previous owner didn't know about the accident. He told me he had problem with the 4wd but replaced the push button switch board inside the cab and that it fixed it. I read online where the reduced engine problem was from a bad throttle position sensor so I replaced the sensor and the wiring harness. It did nothing. I am wondering if this could just be one huge wiring issue from the accident or is it just a multitude of small problems I need to fix.
This has been bugging the crap out of me it happens to us guys that fix cars. You said this has true duals meaning exhaust. Does this have one of those things plugged into the aldl or where you hook the scanner up inside the car?
If it does take it out and see if you have the same problems. A lot of these GM products get screwed up when these things are plugged into the car. Either that or there is some kind of wiring issue with the passenger seat. That is causing this or any other place that eh wiring harness has been modified like an alarm system that was installed that isn't factory unit. Was this answer. I think the throttle actuator is the problem and because it is not functioning properly it is causing other codes to pop up.
The power train control module communicates with the TAC and because the TAC isn't working well the power train core appeared. I checked all of the wiring between the tps sensor and the TAC and also between the pedal position sensor and the TAC and all wires have good continuity. I just ordered a TAC online and hopefully that will fix it!

The older style ignition switch on the through trucks exhibits a different list of symptoms associated with the failed part.
On the and newer Chevrolet Silverado, Suburban and Tahoe trucks we have the same ignition switch problem that exhibits different symptoms than the older trucks. Fortunately, I have replaced enough of these switches that I now bypass my standard logical path of diagnosis and testing. This saves time when I can just jump in and replace the Chevrolet truck ignition switch if the symptoms meet certain criteria. In this brief article will cover the common symptoms associated with both distinctive models of trucks and sport utility vehicles.
In addition, we'll talk about what it takes to replace these parts and link you to some videos so you can see the repairs in action. These parts are expensive when purchased through the Chevrolet dealership parts department. This provides us with an opportunity to not only save money on the parts, but also the labor. Before we jump in let's clarify the difference between an ignition switch and the ignition lock cylinder.
From the picture above, you can clearly see that these remain two separate components. The ignition lock cylinder is where you stick the key in.
When you operate the key you operate a separate part known as the ignition switch. The lock cylinder still remains important because it reads the security code embedded in the ignition key. With that said, when you have problems with the security system the security light stays on solid and the car will often start and die immediately. When you have a problem with the ignition switch you have a bunch of other common symptoms and complaints that we get into in the next section.
The good news is if you have a bad ignition switch you don't need to buy a new key. The Chevrolet truck ignition switch problem on the older vehicles carries a unique set of symptoms.

Drivers of these trucks and sport utility vehicles sometimes complain about how the key operates. The spring-loaded return function of the ignition key is built into the switch itself. Therefore, drivers complaining about the ignition getting stuck and not returning to the run position are looking at a failed switch. Drivers can also complain that the ignition key becomes difficult to operate.
It is the responsibility of this component to also allow current to flow to many important electronically controlled automotive systems. Therefore, some Chevrolet truck owners complain about a check engine light and transmission problems. More specifically, the transmission can shift incorrectly and start out in the wrong gear due to an intermittent power supply to the electronically controlled transmission.U engine code seems a kind of network problem, we try to show one by one the meaning and the solution.
Brief explanation of the U code and definition of U is the bottom side. MFG - Manufacturer Specific codes, which have a '1' as their second digit to indicate they are unique to a particular vehicle make or model. These special codes were deemed necessary by the vehicle manufacturers so they could provide additional diagnostic information beyond the basic list of generic OBD II codes for all kinds of faults, not just emissions-related faults.TECH TIP CAN BUS DIAGNOSTICS
If the engine solenoid valve has an open or short circuit, a DTC is stored. The catalytic converter has an oxygen sensor in front and behind it.
When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. When you see U engine fault code on your engine code reader this description will help you. Final Step: In the definitions listed below, there is a test drive recommended after you've completed any repairs to see if the condition is fixed. Before you take a test drive after a repair, always erase the U Code s first. This will turn the check engine light off and then you will know if the check engine light returns, you've got further diagnostics to complete.

Your gas mileage will also be terrible, so you should try and fix it as soon as you can. So you should chech it on our car models. Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. Spark plugs typically need to be replaced every season or 25 hours of use.
You should also check that the spark plug gap is set properly. If your spark plugs look good, problems with your ignition system can also preventing a spark. These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage.
Parts or components should not be replaced with reference to only a U DTC.

If you know where the sensor is, you only have to unclip the old sensor and replace it with a new one.
Regardless of how you approach it, you should get this fixed right away. Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft.
If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all. Regarding the U code, it would probably be worthwhile to carefully inspect the wire harness near the intake manifold bracket.
This is done most easily from below the car in the area near the oil filter. U DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.

Best guess Could be IGN 0 or 1 fuse. Joined Apr 19, The is on because the dash power is lost. Restore dash power and that code will be fixed. The P is also a power lost code the PCM does see the correct ignition on signal and has the fuel turned off.
You have an ignition problem Thank you Will start in on this the beginning of next week. Good luck!!! Squared away. I didn't have any blown fuses, but the fuses did look discolored so I cleaned then and also sprayed contact cleaner in the fuse box and the power was restored to the dash and truck is working good. Thank you for the help. Joined Sep 28, The discoloration was dark in color on the pins of the fuses. I just brushed them clean, sprayed the electrical cleaner on the fuse box pins and then put the fuse back.
The fuse did fit tight in the box pins. The truck ususally started on the second try now it starts on the first every time. Join the discussion. Continue with Facebook. Continue with Google. Recommended Reading. Read More. Is it possible?
