Had this code come on p2098. Can i fix on my own or should I take it to the dealer. Also has anyone else had this problem? Only 30000 thousand miles and a check engine light? This is b's man

Could just be a faulty 02 sensor 

try switching it out.

ANY mods?

 

[Manuel]

I hope so. I could smell gas when starting. I was running 91 since bought and about 3 weeks ago I out in 87 think this might have caused the problem?

[tbarn]

Any modifications like aftermarket parts or tune?

Verify none of the conditions listed below exist:

P2096 or P2098

• Air intake duct collapsed or restricted.
• Air filter dirty or restricted.
• Contamination of the mass air flow sensor with oil or other foreign material
• Objects blocking the throttle body.
• Excessive fuel in the crankcase. Change engine oil as necessary.
• Rich fuel injectors. Refer to Fuel Injector Diagnosis.
• Excessive fuel system pressure. Refer to Fuel System Diagnosis.
• Fuel contamination. Refer to Alcohol/Contaminants-in-Fuel Diagnosis.
• Fuel saturation of the evaporative emissions (EVAP) canister.

Check, replace O2 then run diagnostics on all of bank 2. I would also check all spark plugs on that side. could be spark related. also you have had this truck from new? There are some issues with burned out cats caused by a engine service flush. 

Let us know when you find out what it was. 

[Manuel]

Not since new but it only had 8000 miles. Going to have it check next Weds. Just didn't want to pay 140 bucks lol. Thought it was something minor.

[Instructor31]

Go to an auto parts store, ask for a quick diagnostic ( should be free )

rent the special socket to replace the 02 sensor before spending so much money at a go.

 

and like one of the above users said, check your MAF sensor on your intake tubing and if you see the smallest of dented on it. Clean it, they’re very sensitive.

[Manuel]

What would I clean it with? also I went to auto zone and that code popped up p2098. I thought it had something to do with the fuel i ran went from 91 to 87 about 3 weeks ago filled twice and check engine light came on. Also about a week ago I was backing out the garage and noticed that I could smell fuel. I cleared the light and it didnt come back on but also i only started the truck for a couple of mins havnt had the chance to drive around.

[Instructor31]

I’ve used those cans of air used to clean keyboards and I’ve had one that had a small piece of dented in it that caused it to throw a code, I just used a small pick ( snap on sells good pick set for things like these) and knocked it off and the code went away.

 

yeah you’ll smell fuel if you’re putting any vehicle in the garage. Fuel carports still escape though the cat converters. 

 

When i I first purchased my truck, I had the issue where I’d get a fault code from all 02 sensors and I had the dealer swap them out. Been fine ever since.

I swear I need to stop reading these post. Today my truck posted p2097 and p2099. Post o2 bank 2 rich. UGH well I got home and removed those codes. Took 2 minutes and 28 secs, but gone....
