Hey guys, CEL came on during road trip. I don't have a scan tool, can you guys tell me how to get the code?

[rdrdr90]

Unless they have changed it, turn the ignition on, off, on, off, on and it should give you the Pcode by the odemeter.

[sharkcohen]

Thanks, I'll try it. Oh, how do I clear it?

[KeavDog]

Find an Autozone

[torred09]

Find an Autozone

That simple autozone will clear codes?

[dodgetime]

turn ignition on, don't start, push stick button for odo reading a few times it should change display to code

last time at autozone they would not clear a IACV code on my f150 said new thang from HQ

[BlackVoodoo]

Probably any cheap code reader for OBD2 will do it, AutoZoo will probably do it for free.

Here's a little more detail in case you don'y have the tricks and tips.

How to Display and Decode Diagnostic Trouble Codes:

How to Display OBD-II Trouble Codes On Instrument Cluster
(Works with or without EVIC).

1. Get in the car, close the door.
Perform steps 2-6 fairly quickly (less than 3 sec's total time).
(The key should not return to the OFF position through this next sequence!)

2. Turn key to 'ON' position
3. then back to 'ACC'
4. then to 'ON'
5. then back to 'ACC'
6. then to 'ON'

If there are any stored codes, they will appear immediately, in place of the odometer.


For instance an "INTAKE AIR TEMPERATURE SENSOR CIRCUIT HIGH" error will set a generic code of P0113.

Many guys forget to hook their IAT sensor up after they install a new intake filter system and crank the engine.

A CEL on the dash instrument display will immediately result.

Once the codes have been displayed, you'll see "-----". If there are no trouble codes, the dashes will be the first item displayed.

After a few seconds, the display changes to "-dOnE-".



Once you have recorded the DTC (diagnostic trouble code), use the chart below to decode:



The DTC code is made up of 5 digits.



The figure below maps the structure or composition of a DTC. With this information it is little easier to troubleshoot a DTC without
knowing the exact description of the actual code.

Important Note!

Generic OBD-II codes start with P0xxx.

OEM MFG DTC Codes start with P1xxx.

Keep in mind that CEL (Check Engine Light) status is for Powertrain (Engine/Transmission) and is primarily for EMISSIONS status functions.
Thus when getting a "Check Engine Light" on the dash, this means engine is out of emissions compliance or an important sensor is out of range or has a malfunction.



NOTE----> Leading LETTER indicator on DTC coding meaning;



P = Powertrain
B = Body
C = Chassis
U = is a communication/Network fault



For those who do not understand or need "ODB-II" explained further, here is a great link to aid in understanding modern day emissions code standard as required

by Federal Law for all automobiles built or imported into the United States;

IMPORTANT NOTE: DTC Codes that start with P1xxx are not generic and arespecific to OEM Dodge/Chrysler/Jeep vehicles.

I cleared a code from a friends car at autozone, they wouldn't clear it but they did loan me the OBDII reader and I cleared it myself.

Thanks.

Damn I got the dreaded P2097. Time to reset this bitch.

[itzrick]

You still have the stock exaust? It says you have a 12 so it aint the tune. I'ld let the dealership worry about it

[sharkcohen]

Damn, pulling the fuse didn't clear it.

[sharkcohen]

Thanks Rob, yah I know, bank 1 too rich. Seems the 2011 392 had this issue, too.

[dodgetime]

too rich on 1 of 4 sensors, post convertor, I'd have to have a look at the rear sensor on the driver side connector

[sharkcohen]

Yes, I'm thinking secondary O2 sensor. I remember on CT last year reading speculation that the electrical contacts of the plug were getting wet and then going bad. Seems the fix was a new sensor and dialectic grease for the plug.
