check engine light on 2006 3.5L
I just bought a used 2006 charger with a 3.5L. It has 24000 miles, runs great, and no check engine light when I bought it. I used the tank of gas in it, filled it up with 87oct gas, and put fuel injector cleaner in the full tank. The check engine light came on yesterday, and is still on. I don't think I need to panic, but I'd like advice. Would injector cleaner and 87oct make this happen? I'm thinking that I will use up this tank, and then refill with 89oct and see what happens before I take it in.Any thoughts

RE: check engine light on 2006 3.5L
Check what code that caused the check engine light to come on by...
Put the key in the ignition (don't start the car)
Turn the key to the Acc position.
* * Do the following quickly * *
Turn the key from Acc to on.... then back to Acc and to on... one last time back to Acc to on.
The code(s) will be displayed where the milage is on the dash and dashes --- --- will be displayed when the list of codes is done displaying.
You can check the codes here on the fourm at this link ODB II codes
I believe aP0403 would be the gas cap thing mentioned in the post above. Anyhew just post up the code and we can take it from there.

do mean to hyjack the thread, but I have a question that pertains directly...
if it is a loose cap or if I were to fill it while it is running does the check engine light reset itself or do you have to do something else to make it go away?

The code will reset after a set number of successful startups without error condition. Of course I don't remember how many times that set number is [&:]
Here are a couple options to clear the code manually:
Most tuners allow you to clear the codes.
Pull fuse 11 for a minute and replace it.
Pull the negative battery cable for a minute and replace it.

RE: check engine light on 2006 3.5L
I too just bought a 2006 SE 3.5 and started runnign 87 gas in it and after 2 tanks got the check engine light. I used my code checker and got a mis-fire on cyclinders and after switching back to 89 and 93 gas it went away. Maybe it makes a difference. BUt, can running on 87 harm your engine long-term?

P0406 Description:
Early Exhaust Gas Recirculation (EGR) systems component s include and EGR Valve, and Engine Control Μodule (ECΜ) Controlled Vacuum Switch Valve or EGR Solenoid and an EGR Vacuum Μodulator. Depending on the engine and driving conditions, the ECΜ will control the EGR Solenoid which will operate the EGR Vacuum Μodulator to regulate the opening and closing of the EGR Valve. The EGR system on recently built vehicles uses a step motor to control the flow rate of EGR from exhaust manifold. This motor has four winding phases. It operates according to the output pulse signal of the ECΜ. Two windings are turned ON and OFF in sequence. Each time an ON pulse is issued, the valve opens or closes, changing the flow rate. When no change in the flow rate is needed, the ECΜ does not issue the pulse signal. Α certain voltage signal is issued so that the valve remains at that particular opening.

Possible causes:
- EGR Valve clogged, dirty or leaky
- EGR valve damaged/defective
- EGR volume control solenoid valve
- EGR temperature sensor and circuit
- EGR volume control solenoid valve harness is open or shorted
- EGR volume control solenoid valve circuit poor electrical connection
- EGR Valve clogged, dirty or leaky
- EGR valve damaged/defective
- EGR volume control solenoid valve
- EGR temperature sensor and circuit
- EGR volume control solenoid valve harness is open or shorted
- EGR volume control solenoid valve circuit poor electrical connection
When is the code detected?:
- An improper voltage signal is sent to ECM through the valve
- An improper voltage signal is sent to ECM through the valve
Possible symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine hesitation
- Engine Light ON (or Service Engine Soon Warning Light)
- Engine hesitation
