    Crazy Stuff on my 08 Hybrid Tahoe - Revs up and Dies

    Thanks for all your details - and you're right. The Scanner was the mechanic's and he's $140 long gone. Surprised he actually charged me (especially because he said if he knew it was a hybrid he wouldn't come out, but I clearly told him it was), but I digress. I have a jumping battery that...

    I'm going to close this thread because I found the BCU fuse issue. Started a new thread with the TECH readouts. I guess I can't close the thread, but let's reconvene on the new thread. :) Thanks!

    Crazy Stuff on my 08 Hybrid Tahoe - Revs up and Dies

    This is an offshoot of another thread I started thinking I bricked my Tahoe after putting in an aftermarket radio. I since realized that I blew my BCU fuse. Replaced it and it started fine, but then redlines and dies. I've paid two mechanics to come out (because I can't take it anywhere) and...

    I have some of those pids on Torque. Would not have helped in this situation, I don't think.

    No Crank

    Mechanic just told me he can't make it back 'til Friday. Blech. Yeah - I can clear the codes and start it again with my little OBDII, but I'm a bit scared. Truck has 300,000 miles on it. But replacements are $$$

    No. :( not yet.

    The 2A fuse went to the Body Control Unit. No idea how it blew unless I did it somehow tinkering with my aftermarket radio.

    No Crank

    OK - so a really weird development in this situation. We discovered that the 2A BCU fuse blew. We replaced it, and the truck started up just fine... BUT THEN - after idling for nearly 30 seconds, the engine on its own revved up to redline. When we cut off the power, it made some crazy...

    08 Tahoe - CD Player Busted

    Yeah - I did that, and it was pretty plug and play, but it bricked my Tahoe. Now I have an anti-theft error that I can't clear and I can't crank the engine. The new head unit was barely OK. Over time (like 20 minutes) it would stop sounding good and sound super staticky. Came with what it...

    Thanks. Saw the other thread. Tried everything I could, including putting the original radio back in. No dice. May have to call a mobile tech to it. :(

    No Crank

    Having some interesting issues with my 08 HyHoe. I replaced the OEM radio head with an aftermarket. Now the truck won’t start. The security icon is on. It won’t turn over at all (hybrid owners know these don’t “crank” in the traditional sense). Battery shows 12v. Won’t accept a jump start...

    08 Tahoe - CD Player Busted

    Hi all, My 2008 HyHoe's CD/DVD player busted. CD couldn't be read or ejected. I assume that the mechanism failed somewhere halfway between in and out. Anyway, the stuck CD was making an annoying clicking sound for weeks before I finally forcefully pulled the CD out (yeah, not exactly a...

    The lurching is slowly returning. Argh.

    2008 Tahoe Hybrid 12v Battery Constantly Dying

    Did these come from the factory with quick release? Mine had them when I bought it 2nd hand. They were eventually replaced for similar reasons. These are good trucks. Just need a little TLC. Coming up on 290K now with: 1 new engine, 1 replacement Hybrid battery, 1 replacement AC Compressor...

    P0171 P0174

    Just in case anyone runs into this on their HyHoe, note that this will prevent the vehicle from entering AutoStop. In my case, the PCV came unattached. Popped it in, error went away. FWIW...

    Trouble shooting P0171 P0174 Bank 1 and 2 too lean

    I know this is an old thread, but if it helps anyone, cool. My pcv valve came off. That was all. Codes reset.

    P0301

    It fixed the miss immediately. The lurch slowly returned. Sidenote: I've been having issues with my cruise control for years. Never thought much of it. It worked or it didn't. Whatever. Eventually, I took my '** to my local hybrid "expert" and he swapped out the brake switch sensor under...

    Are you having ANY issues with your cruise control?

    Lurching and Hiccups

    Had my #1 coil go out. I replaced it and the lurching seems to be all but gone. But I also replaced the brake sensor switch because my cruise control was super intermittent. Mechanic told me that switch could have fixed the issue as it ties a lot of the various computer systems together...

    P0301

    Interestingly, the bad coil was different than the rest. This one I did myself for about 1/5 of shop cost. It also seemed to reduce the lurching I've been experiencing when it switches from ICE to Auto Stop.

    Maintenance Manual

    I was probably ripped off if book time is 3.2, but oh well. Sometimes you have to take one to the gut. So, the compressor DID die (I know the difference between the typical electrical whine of the compressor vs an imminent failure). It lasted about two months with the ear piercing sound, but...

    Maintenance Manual

    Hi all. Does anyone know where I can purchase or rent a service manual for the 08 Tahoe Hybrid? All basic aftermarket manuals I've come up with don't include the Hybrid. Specifically, I need to know the hours estimated to replace the electric AC Compressor.

    P0301

    Hi Interworld. Pulled a P0301 today. Replaced spark plug in cyl 1, no change. Swapped wire from Cyl 3 with 1 and no change (May have damaged wire). Swapped coil pack with Cyl 3 and added P0300, but NOT P0303. I figured if it were a coil issue, I'd get a P0351 instead of P0301. Thoughts?

    What is this part?

    You were right... It was hard to see the bottom of that part in the photo on the link you attached. Also saw it called "Lower control arm". $28 from Moog and I believe an easy replacement. I don't think it requires pressure. I think I did this before. :( But yes, it's a 2008 Hybrid. And...

    What is this part?

    That's what I kept coming up with, but it's not (unless it's been redesigned). Mine is a U-Channel facing down.
