    that is incorrect P0420 will have bank 1 and bank 2 P0430 just confirms this (Not always though) as I had P0420 and P0430 often and still was able to pass CALIFORNIA smog testing it turned out I had a faulty sensor else where that caused it (faulty Barometer sensor I was getting P0069 ) I would check upstream as well i.e spark plugs , MAF MAP etc... these can trigger CAT code and the P0135 code can trigger a P0420 code this is why it's good to verify the CAT temperature first if it stays about 200C or so then it's bad or cracked honey cones it should be 325-400C minimum (unless DFCO cycle)... Also there is other options for catalyst converters.... such as a HIGH QUALITY after market MAKE sure it's a 50 state Certified model here is the legit california aftermarket data base this will help you buy a certified catalyst converter for your truck(THAT MEANS it will work 100% compatible No guess work) Aftermarket Catalytic Converter Database Also you might still have some warranty left as emissions is 8 years/80,000 miles ASK for a print out at a local dealer to see when the WARRANTY was punched if your lucky you can make a claim... and have it fixed for free if your slightly passed that GM might help a little with the cost( or a lot)

    the cat is oil poisoned what is the temperature are you getting from the cats once it's warmed up?

    does it even try? also check the VLOM bolts might sure they are nice and snug(sometimes they roll out loose from the factory) there was electrical changes for the 2010 model that is why they have VVT (way better emissions output compared to non vvt models)(NO2) that is why you buy the computer and harness

    is this the legacy 48volt system or HIGH voltage 2mode hybrid? the 48volt system is standard lead acid batteries 4x12v =48v

    Clean the A/C condenser that is the solution to your overheating problem ..... bet its clogged with varies insects ????? be gentile I use a toothbrush and dawn dish soap(just a drop is good enough) in a squirt bottle distilled water is preferred if you don't want deposits left behind I can stick my hand through the grille though but you can remove yours though I clean mine every 6 months can't risk overheating an aluminum block..anyways my A/C gets cold quickly with in 15 seconds it's all ready blowing cold air Remote start by the time i get inside it's all ready cooled off..

    those old 42 volt hybrids are worth a pretty penny Word on the grape vine is GM was buying them back..(possible secret recall??)

    chevron has techron D for iesel so yeah you can get TOP tier iesel fuel sorry my button does not work sometimes i have light weight tires 31 pounds ea on the drive wheels less mass to rotate (the more mass= rotational drag, the more drag it has/ more fuel it uses ) also the tires are pumped to 44psi that by it self is worth 10% gain in MPG for free

    i only run mobil or chevron they must pay the delivery man a bit more to pay attention i had bad luck getting only 87 octane out of the 91 pumps at Shell, Arco stations (tested at lest a 1/2 dozen stations issues with AFM running 87 octane (will hyper loop on and off with 87 octane) MPG drops to 18.5MPG I can actually accelerate with AFM v4 starting from first gear with 91octane I can get upto 31.2MPG with 91 octane on the highway assuming everything is working in perfect harmony 26-29MPG on the highway is typical for me while running normal speeds 75MPH ... it might have something to do with the traffic I get better MPG when there is more traffic as 40-45MPH is the sweet spot (it's not safe to drive this speed with very little traffic) that is when i get bigger numbers MPG wise in the city it's been less as i have been running the AC (Rather use a bit of gas then cook inside the suv) in the winter my mpg is better 22-23range

    MAF or IAT sensor is bad more then likely common failure on the NBS and NNBS I had to replace mine(IAT was bad I had the combo version) as it would backfire on start up,full throttle and/or oscillate idle rough idle(misfire on idle) randomly
  10. bg1988
    yeah even if that was from the timing chain NOTHING would happen nor any damage to the engine as this is a Non-interference engine the heads have a notch cut out for the valves dealers are playing you saying other stuff is damaged the only way to know for sure is to crack open the engine P0016 cam to crank misalignment I highly doubt the CAM went out these are of much higher quality then what you get on a normal rig it's very specifically designed for Heavy Duty usage i.e auto stop.. and HIGH SPEED starts remember these rigs are started by a 60kw motor not a 12volt starter that start speed can be about 1500 to 2,000 rpm from auto stop these rigs have HIGH performance corvette oil pumps in them not the "normal ones" P0016 Malfunction criteria: 2 cam sensor pulse more then 11 crank degrees before or 11 crank degrees after nominal position in one cam revolution . a the phaser sensor is broken or slow /broken bad wires or it skipped a few teeth also with the P0106 it could be the MAP sensor or MAF/IAT (mine was the MAF/ IAT when i got that code) there is no real risk with the HV unless you are messing with the HV battery, HV wires or inverter just pull the HV disconnect switch and keep it on your person so no one can energize the system..

    what color was the plastic?
  12. bg1988
    you will need an entire swap out from a donor truck including the A/C wires computers it's going to be a lot of work i bet there is nothing wrong these can last i have seen one with 290k miles.. and there is plenty with 200k+ on them use 91 or 93 octane fuel from mobil/exxon or chevron/texaco also i would check the battery cables they are probably dirty as well there is several of them if you not getting at lest 14.8-14.9 volts on cold start, you will have issues \ i would also inspect the cable from the engine block to the chassis it may have fraying or dirtyness also inspect the terminals for crimp damage or opening up damage You can do a Hemi 5.7L swap as well must be a version from the hybrid model.

    WRONG the Issue is GLASS will break from the heat or from the hot glass touching cold water or hot water touching cold glass(less likely to break but can happen) it's called thermal shock.. there can also be scratches that cause it to "explode " the truck has laminated glass that is why it did not go everywhere.. don't forget GM is known for cars catching fire and parts flying off of them i guess in this case it's parts flying off of it.... this sums it up

    5k is good you have 8qt
  15. bg1988
    Not true my suv vibrated heavy at 67 to 76mph after replacement of the pads and rotors (turned) it went away I did not feel anything from the pedal
  16. bg1988
    what is the OCI for that 78k?
  17. bg1988
    Change your oil often 6k miles (you have 8.5qt so it can go a bit longer then the 6qt ones (4,000 miles OCI is recommended) ? At it's current mileage its more then likely has seen well over 200,000 Engine Start/Stop cycles (AutoStop) I have a 60,000 Watt 300Volt AC 3 phase starter no worries there.. AND burns NO oil because it's changed often a keep clean with NO SLUDGE.. NO wear and tear on the engine OR make sure the shop actually changes the oil lot of the time THEY don't change the oil at all..
  18. bg1988
    they had this for a while circa 2008* so you can keep AFM mode much longer *on the hybrid model only.. basically they ported over things from the hybrid model to the newer non hybrid models such as the electrical power steering, brake system (see vacuum pump) ,VVT system and extended AFM. this is nothing new having the secondary system... that one time I lost complete power the brake system locked up ( all 4 wheels locked up aka Fail Safe)

    I think i told you guys too keep your engine oil clean
  20. bg1988
    I win i get 22city-25MPG highway next time buy the hybrid 6.0L engine 379HP @5100RPM 472ft-lb torque @4100 rpm the minimum torque is 320 @ any RPM even with v4 she will spin the wheels at a dead stop even done it in front of a police officer (happened accidentally while turning) i did not get a ticket since the officer was too busy giving a ticket to someone else!
  21. bg1988
    92,005 miles Still going Strong Burns NO oil No oil consumption, No SLUDGE.. Engine Oil stays clean to 4,000 4,000 Mile Oil change interval (±50 miles) Hybrid Vortec 6.0L LFA Aluminum Engine (LS2 based) 80HP Electric motor 379HP 472 ft•lb torque combined output ? she runs a custom blended mobil1 5w30 (5qt) & Mobil1 0w30 (1qt) and a steady diet of Mobil or Chevron Fuel, 91 octane only for Maximum Performance Piston Style Flat Top, with valve reliefs (for VVT duh) Casting Numbers 799, 243 Material Aluminum

    welll GM did increase the oil capacity to 8.5qt that in it self says a lot obviously they are trying to use it as a patch also the Oil life monitor has been updated as well in the newer ones to a shorter OCI
  23. bg1988
    keep the fuel tank low gas caps do nothing to stop people from taking the gas they will just drill a hole in the tank
  24. bg1988
