    Fog lights - SOLD

    Still have these, Chris? Brand? I assume these were for your 2004 Tahoe, same as mine (LT?). Shipping price to 80134?

    Fuel tank pressure vs. evap purge

    Let's not confuse fuel rail pressure with fuel tank pressure.

    2003 GMC Yukon traction control/limp mode

    BTW, it's a PEDAL, not something you're trying to sell (e.g., peddle). ;) There is a TSB for the throttle body, including an updated "calibration" for the PCM. (Verify your vehicle first, though)...

    At a loss with electrical/mech problems - 2015 Tahoe LTZ

    Wouldn't hurt to do a standard voltage drop test.

    Problematic P2135 code

    Note that the APP #1 and #2 (and also the TPS #1 and #2) values are inversely related; when one goes higher, the other goes lower. In the graphic that @TJ Baker posted in #10, they each vary from their respective high/low voltage by the same amount. In other words, when one APP value is 1v...

    Fuel tank pressure vs. evap purge

    Good question. I was too elated to check what happens to the I/M, and thankfully haven't had the need since.

    Fuel tank pressure vs. evap purge

    That surprises me, too. When my evap problem (fuel pump gasket) was corrected, mine reset and cleared the CEL/MIL within two miles on the first drive, so I'm not sure how that works exactly.

    Take a look at what @TJ Baker posted in the prior message. 15-85%.

    Fuel tank pressure vs. evap purge

    Well, if you want the evap to be ready and to run, avoid filling the tank. Evap won't run if the tank is lower than 1/8th or higher than 7/8 full. Half a tank is safe.

    Try to not start a bunch of threads about similar issues with a vehicle. This could have been added to your previous thread.

    Fuel tank pressure vs. evap purge

    You can also just blow through either valve with lung air to test. With the valves out of the vehicle circuit, the purge valve should open with 12vdc applied (polarity doesn't matter) but be fully closed with none applied. The vent valve is the opposite -- open with no voltage, but closed...

    There are just some days I wish I didn't turn wrenches

    I thought this was a good idea, but last time I suggested that it was laughed off. Keep buying that Bactine. Whatever. ;) https://www.tahoeyukonforum.com/threads/there-are-just-some-days-i-wish-i-didnt-turn-wrenches.142050/post-2023293

    21 Yukon XL Service TPMS System?

    A scanner that can read the TPMS sensors from the tire stem (like when setting the tire positions) should read the battery health but I don't think they read a specific voltage.

    Auto Stop Tried to Activate Even Though It Was Turned Off

    Gas filter

    Most, if not all, of the GMT800 Flex Fuel vehicles have an external fuel filter along the left frame rail, right near the fuel composition sensor.

    2013 tahoe rough start/stumble.

    Long-term fuel trims indicate very rich condition on both banks. Measure the fuel pressure on the rail, key on, engine off. What fuel are you using, specifically the ethanol content. E0, E10, E15, E85? Will your scanner show the fuel alcohol (ethanol) content, and does that somewhat match...

    2011 tahoe driver front door replaced, and now an SRS driver door service air bag code

    My bad. Did the OP ever disclose the specific code that's being set for the SRS? It's like pulling teeth. I'll shutup until I see details.

    2011 tahoe driver front door replaced, and now an SRS driver door service air bag code

    For the SRS code -- if you're still interested in that one -- which your Tech 2 shows as B0013-0D, that's a fault in the steering wheel circuit for that airbag. Might be a clockspring or connector issue, but look at the link below and scroll down to the conditions and diagnostic path for that...
