What did you do to your OBS GMT400 Tahoe/Yukon Today?

[retorq]

Drove it to town to get parts for my other projects.

Fixed all the lights on the front, starting to work on the heater control valve.

Started it and drove it to gas station and drove to wally world

got a new door check strap for the rear cargo door.

there is a e-clip that holds that pin and bushing together in the strap and on the hinge on the body. An e-clip that lmc wants to charge $18 for. What a rip-off.

Got her (many) codes scanned today. Good lord, I'm in for quite a ride with this thing.
P0340 - Camshaft Position Sensor (daunting)
P0141 - Sensor heater malfunction, Bank 1, Sensor 2 (typical)
P0122 - Throttle Position Sensor low input (Replace sensor?)
P0414 - EGR (ugh, can't I remove that?)
P1351 - ICM (Could be false code triggered by other problems)

What's funny is that even with all these trouble codes, she runs great until warmed up. lol.

PM'd tho would seriously look for a busted ground somewhere.

 

[Phantom240]

Busted ground because most have that 5v reference voltage?

 

[SunlitComet]

it can happen but not always. sort of hard to explain but kinda how you exterior lighting acct weird when a ground is not right. but by all means if you you can probe or have a scan tool that can read like i have then you should be able to see what the reference outputs are pushing.

 

[Phantom240]

I could do basic troubleshooting of the signal by probing the wires coming into the sensor to make sure that there's voltage coming in, and that it's not reading an open circuit on ground, correct?

 

[SunlitComet]

yes but you would have to disconnect the connector and test thru the terminal. you cant exactly back probe the connectors used these days. unless you have wire puncture test probes.

 

[Phantom240]

And those are fairly expensive, lol

Autozone sell the door checks to I think $ 12.00 I pocket a couple from the jnk yrd.

I made my truck go from this-->

To this-->

Rough country add-a-leafs in the back, and rough country leveling keys up front. Ended up with 1&3/4 inches and it's awesome down the road!

they arent that good. the ones from dormon have a tendency to have the end snap off.

 

[Chevrolado]

Put some new AC Delco spark plugs in. Definitely needed it based on the visual inspection on the removed ones. They were pretty well used. Nothing out of the ordinary, but well used.

Now I just need to figure out where that "knocking" sort of sound is coming from..

 

[SunlitComet]

still gotta finish doing mine only got 4 of them done the older copper cores are pushing .070 gaps. still fires with no misfires but cant last forever.

 

[edward61]

I got new tires for my hoe and also had an alligment done.

 

[Phantom240]

Lookie what we have here
