WOW ... amazing what a few years did to prices! Way down from panic central in '11.

Found fuel for 2.16 in west florida. It 2.69 around indiana

 

Sleeping in it. 42 degrees outside is good sleeping in truck weather.

Sound like EVAP codes to me. Stupid useless system. It's good at cleaning out your wallet in states that test for emissions, though ...

 

I get to try and fix a "small leak" on a '06 Impala today. I'd better find some blood pressure medication ...

 

 

Ahh correction - those are lean codes, bank 1 and bank 2. WTF? On a '10 ???

Both banks lean. I'd start by testing fuel psi.

 

Evap isn't all bad, for one thing your fuel doesn't go stale as fast. Very easy system to troubleshoot and fix in my limited experience with it.

Yes bank 1 and 2 lean truck is running fine

That's what I hate the most about OBD-II. The thing runs fine, so the light is on due to emissions. Now if you live where they don't test, then it's all good. But, if it's sticker time, now you've got to waste time fixing it. That burns my ass ....

 

 

 

 

 

Every EVAP system I've tried to fix was like finding a needle in a haystack. Without a bi-directional scan tool or a smoke machine, it's a matter of guessing correctly. I'd have better luck getting struck by lightning while winning the MA state lottery at the same time ...

 

I might try to rig up my 2-stroke leak down tester on the filler neck & see what I come up with. Finding a 1 psi leak should be fun even still ... Might just throw a gas cap at it and hope for the best ...

Gonna suck if you find out E85 is causing system problems even with an FF truck. That won't be good news for anyone.

 

Hope it's something simple.

 

 

Dump in a few cans of seafoam and BG44K and run it hard and hope for the best?

I am thinking dump O2 sensors and add some headers. No inspections here

Nice - you're lucky!

 

Good news for me - just found the codes on that Impala are bank 1 sensor 2 codes (o2 sensor).

 

Gotta love OBD-II! Sensor has no bearing on how the engine runs, but because we live in MA, the 85 year old owner on a fixed income gets to shell out $68 for a new one (wiring and fuse good). :nonod: Needs a sticker by end of month.

    • No such thing as regenerative braking on a pure ICE vehicle.     Regenerative braking is the re-capture of energy from electric motors and stores it in the battery pack.  So hybrids, PHEV and EVs have regenerative braking.     What you are seeing is the charging system changing modes is all.  Its likely entering charge mode for some sort of reason is all.  All of the charging modes will be listed below.   As for L10 vs D.  L10 turns off automatic grade braking.  L10 puts you in control of grade downshifts where in D it will automatically do it based on brake pedal position and other factors.  Otherwise L10 and D drive exactly the same aside from that one aspect.    Battery Sulfation Mode The BCM will enter this mode when the interpreted Generator output voltage is less than 13.2 V for 45 minutes. When this condition exists the BCM will enter Charge Mode for 2–3 minutes. The BCM will then determine which mode to enter depending on voltage requirements.   Charge Mode The BCM will enter Charge Mode when ever one of the following conditions are met:   Windshield wipers are ON for more than 3 s. Climate Control Voltage Boost Mode Request is true, as sensed by the HVAC control module via serial data. High speed cooling fan, rear defogger, and HVAC high speed blower operation can cause the BCM to enter the Charge Mode. The estimated battery temperature is less than 0°C (32°F). Battery State of Charge is less than 80%. Vehicle speed is greater than 145 km/h (90 mph) A current sensor malfunction exists. System voltage is determined to be below 12.56 V When any one of these conditions is met, the system will set targeted generator output voltage to a charging voltage between 13.9–15.5 V, depending on the battery state of charge and estimated battery temperature.   Fuel Economy Mode The BCM will enter Fuel Economy Mode when the estimated battery temperature is at least 0°C (32°F) but less than or equal to 80°C (176°F), the calculated battery current is less than 15 A and greater than −8 A, and the battery state-of-charge is greater than or equal to 80%. Its targeted generator output voltage is the open circuit voltage of the battery and can be between 12.5–13.1 V. When fuel economy mode is active, the generator is not charging, only maintaining open circuit battery voltage. The BCM will exit this mode and enter Charge Mode when any of the conditions described above are present.   Headlamp Mode The BCM will enter Headlamp Mode when ever the head lamps are ON (high or low beams). Voltage will be regulated between 13.9–14.5 V.   Start Up Mode When the engine is started the BCM sets a targeted generator output voltage of 14.5 V for 30 s.   Tow/Haul Mode (if applicable) Pressing the Tow/Haul Mode button located on the center stack, the vehicle system voltage is raised and the remote (non-vehicle) battery will be charged. Having the headlamps on will raise the system voltage and if the Tow/Haul button is applied it will not serve any purpose. The voltage is regulated between 13.9-14.5 V.      
    • Hello from Australia Just sharing that there is now a way to delete the active shutters entirely with just a plug in module. Opens up tons of room to light bars etc.
    • I have an observation and a question... 1) I watch the voltage closely because I have had to dial in the cut-in/cut-out voltages of the battery separator to my camper.  The "smart" charging drives me nuts.  Anyway, I noticed that when coasting for a while, and especially if lightly using the brakes (though not necessary), the voltage goes up from mid/high-13 volts to mid/high-14 volts.  Then it drops back down after stopping or going again.  Consistently!   The only explanation I can come up with is REGENERATIVE BRAKING!  Well, maybe that's a little bit of an exaggeration, but it's certainly free extra battery charging.   2) Driving on mountain roads I will use L and vary the max gear.  Things straighten out and I end up in L10.  Sometimes I leave it there for a while.  Is there any difference between L10 and D?   
    • Do you think this width might affect the chalk test with a higher pressure closer to 65psi? I think lowering the pressure makes sense to get the tread to lay flatter
