**Diagnostic Trouble Codes**

[Rich J.]

Just re-installed my hypertech and it read code #C1269. I tried to google it to no avail. The P0155 and P0135 are O2 sensors I believe?

[SA-S10]

Have you tried this site? OBD-II - On-Board Diagnostic System

[amraam35]

if u have the engine running when up jump term. A and B, just like to check the codes, it tells u if its open loop or closed loop. anyone know what these signals actually are

[never_finished92]

i just made a thread, and then saw this one...oops

P0410 - Secondary Air Injection System

thats the code i got, what could be wrong?

[roachrod]

I've got an 02 blazer extreme with a P1345 code, which is camshaft and crankshaft corrilation. I replaced both the camshaft and crankshaft sensors, and the thing still throws the codes. Any ideas?

You need to have the dealer do a crank re-learn.

You may be able to do it yourself by elongating the distributor hold down hole. But that is just guessing. Or your distributor may be off a tooth, or you may have a ton of slop in the distributor gear, or timing chain.

r these just general gm codes because i didnt know any s-10 turbo diesels, glow plug codes, turbo codes, injection pump codes? just wondering

These are obd2 codes, it is mostly standard. Some are manufacture specific.
OBD-II Trouble Codes

They did sell s10's with turbo diesels though, but not in this country.

[ThatOneGuy]

wow i dint no they had diesel s-10s and how can i get one??

I just scanned my Jimmy I just bought and this was the only code that came up.

What does this mean? Do I have to replace the EGR Valve?

Need help, thanks.

I need an explanation for a B2600 trouble code on a 03 4.3 auto.

[gmcjimmy96]

i've got codes 700 and 1100....what are they, i know code 700 is transmission control system..buuut what is that??? and i cant find 1100 on the chart.

[Rockrz]

OBDII Codes is for '96 and up, right?

[ewf3]

right

[droppedss]

P0756 - Shift Solenoid B Performance or Stuck Off. I replaced both shift solenoids..still does it after driving it for a bit.

[cmittle]

Is there a way to read the code in my '88 S10 pickup?

Thanks,
Cory

[itscypha]

Thats what i got in my 95 blazer... what should i do to fix this clean out the o2 sensor check the wires or just replace it?

[dropit]

ok i have a 95 4x4 jimmy 4.3 has the w code motor but is the obe 2 system and im getting the codes p0700 and a p1100 i was wondering do u know what that might be i know the p0700 is Transmission Control System (MIL Request) but what is this

[2.5Dime]

I was wondering if i have one and where the aldl would be on my 91 s-10

[2.5Dime]

I got a code 22 which deals with the tps is my only option to get a new one?

btw, any way to check codes manually (without scanner) for OBDII+ Jimmys? don't have scanner, and those mechanics that have, just for conecting it ask for 35+ if you are lucky, cause they think it's a SUPERHIGHTECH DEVICE...

No, you need some sort of scanner. The price is coming way down on the very simple ones, like this:

Good to know, by the moment a simple one will do the job, thanks for that!

[layin20's]

I'm getting codes P0102 and P1133 what do they mean?

[94s-dime]

I have a 94 s-10 with the 4.3L engine code Z. i am getting a 35 - Idle Air Control (IAC) System code and it only comes on when my truck is idling hence the code. the problem is i have no idea what the idle air control system is and how the heck am i supposed to fix this problem? does anyone know what the IAC system is and how i can fix it??

[moriskod]

I have a 92 S10 Blazer. Engine runs fine until it gets warmed up, I shut down then restart. I will be driving along and it will "studder", and lose power. Check engine light will come on. When I retrieve the code it is code 41. Having a little trouble getting information on that code. On this site it says 41 is "camshaft sensor circuit" but I'm not sure the 92 has this?

[z06s10]

guys im getting three codes P1133, P0133,P0440 on a 97 2.2 s-10 I have taken to shop 4 times and seems they keep trying to put gaskets and seal my heads saying that it was exhaust leak and its fixed but yet I cont have problems. Is this the 02 sensor and should that solve this snowballing problem. Truck runs but low performance and seem to have low backpressure linking to a obvious exhaust leak and even sound like one but with that I am soooo confused as to how it could be a 02 sensor . Any help or advice would be great.If you could post most replies in PM that would be great

[ryanmooney]

i got a code P0446 - Evaporative Emission Control System Vent Control Circuit the guy at autozone asked if my gas cap was tight and it was should i just go out and buy a new gas cap or what should be doe fill me in i'm sick of that orange light always being on

Yes, buy a new gas cap first - possible easy solution. If that doesn't fix it, Click here.

Some more good info from another post. This applies to OBD1 vehicles when checking by the paperclip method:

4 flashes for the num 4 then 3 flashes for 3 quickly each time for 3 consecutive

If there is another code say 24 you would get 2 flashes quickly and then 4

Finally when all the codes have been flashed OR no codes are present, you
should get a final code of 55. 5 flashes quickly followed by another 5 flashed

Simple, huh.

[mcdanida]

Blazee, you sir, are the MAN for posting these trouble codes! Thanks so much!

Now I must figure what my SES light code is for my 2003 S-10? It came on this morning when I abruptly stopped in traffic, almost rear-ending somebody.

Any guesses out there?

If it has the secondary air injection system, that would be my guess.

BINGO Yogi, the error code was P0410 - Secondary Air Injection System. Is there anything I should worry about? I've reset the SES light and the error hasn't repeated yet. Would this be common in a situation such as mine, creating maybe a false error?

[Yogi]

It's not likely a false error. Those systems have definite problems. Water accumulates and corrodes the check valve and the pump. Do an advanced search on Google for "secondary air system" on S10Forum.com and that should give you the info you need.

[mcdanida]

Yogi, while I have you here, I want to ask another question - maybe you can direct me to a better forum? Or know the answer yourself. My A/C works GREAT! Maybe too good to be honest; the vent air is pumping a very cold 39F.

There is a problem I think. The accumulator/dryer is building way too much frost, from 1/16" to 1/8" of ice. It travels into the evaporator which is covered so I'm not sure what the ice build looks like on it, I assume about the same?

I tested the pressure and it's a good 30 psi (spec is 25-44 psi). I am in a very humid and warm environment (Virginia), so condesnation is expected. I have been told I want the dryer to sweat real nice, but not freeze.

I've been told a number of diagnoses, low freon, overcharge, thermal clutch switch, etc. It is true I do not see/hear the compressor cycle or clutch engaging/disengaging, so I assume a constant "on", which makes sense to me. I also notice a "squeek" from my serpentine when A/C is on and I start moving from a complete stop - wonder if that's some type of resistance on the compressor pulley for whatever reason?

Anyway, your thoughts? Is this a "don't fix it if it ain't broken" problem?

The accumulator should sweat, not freeze. Seems like a frozen accumulator would have a lower pressure than 30#. Comp. clutch should be cycling also. Definitely needs to be fixed. I would say it's a bad low pressure switch, or overcharged. I used to work on R12 systems, but I'm no expert on R134. You might try posting in the S-10 section.

[mcdanida]

Thanks Yogi, I suspected it could be the pressure switch. Question: do I have to evacuate the system in order to swap the pressure switch?

I also notice belt squeeking while A/C is running, but not while turned off, that tells me there's resistance at the clutch/compressor pulley? I'm hoping NOT to replace the compressor.

Something also funny, the system sweats PERFECTLY as it should when I run the MAX A/C? I have no problem doing that in this heat!

The pressure switch is on a schrader valve (like a tire stem) so you don't have to evacuate to replace it.

Squeaking belt sounds like an overload for some reason.

It's sweating on Max A/C? I would expect that if it were freezing that it would freeze on Max A/C. When does it freeze?

Edit : We're mucking up the sticky on diagnostic trouble codes with a lot of b.s. about A/C. Why don't you start a new thread in S10 section and pm me when you do.

Yeah Yogi, I didn't mean to go off track in here, I started a new thread:

The info that I copied does look suspicious. According to the list, code 55 is a faulty ECM. I'll see if I can get BG's to clarify.

[bg's]

I need to give a HEADS-UP on the final code for
the code run regarding OBD-1. I stated code 55 down
was the final code. THAT IS INCORRECT. Code
12 x 3 is the START OF THE CODE STREAM
and ENDS WITH CODE 12 X 3 as the final
code before the code stream runs again.

Sorry bout that. Didn't mean to mess anyone up.
Thanks for letting me know, Y.

I am constantly getting the following error:

P0410 - Secondary Air Injection System

It occurs everytime I begin an abrupt stop in my 2003 Chevy S-10 LS, or bogging down in a higher gear.

The SES light is beginning to annoy me and I'm tired of disconnecting neg. terminal for 20 minutes to get rid of light.

Any advice to the fix?

Do a search for "Secondary air system" in titles only. That will give you plenty of info.

Replace your thermostat and that may fix both codes. The sensor for P0155 is in the exhaust pipe on the passenger side, just downstream from the exhaust manifold. Click here for more info.
