I have 200 miles on my HC and got a check engine light on today after a little bit of spirited driving but nothing too crazy. No high RPM shifting or launching the car. All gages read perfect, thoughts?

RUH roh did you punch it too hard before 500 miles? Check to see if there's some error code in the log event

 

[CO Springs Sublime Kitty]

I have a P0069 code. How do I check what that means?

Well since its a new hellcat then it can't be a dirty filter UNLESS it came dirty since it was sitting at the yard for too long before it got delivered to your dealership. If that is the case then replace the air filter and reset the code and see if it happens again. If it does happen again after that then It could also be the intake air temperature sensor.

 

[CO Springs Sublime Kitty]

Ok thank you so much! I will have the dealer replace it since it's brand new!! Plus then they can reset the code, right?

Yeah they should be able to easily. Have them replace the air filter first and make sure there are no air flow problems. It may be other causes of the code hope someone else chimes in.

 

[CO Springs Sublime Kitty]

Ok will do. How is is that you can tell what the code means? Do you have a master list or something?

Well i have some codes in my book and I researched some from the net over time.

Theory of Operation

The 6.2L engine uses several sensors to monitor the air pressure and temperature throughout the intake air system. The PCM uses this information to help calculate fuel delivery, ignition timing and Supercharger control. The PCM runs diagnostics to check the rationality of the sensors. The Supercharger Inlet Pressure Sensor is the centralized sensor in the system and is the main sensor used for the rationality diagnostics of the airflow before and after the Throttle Body.





Individual MAP/Pressure Sensor rationality diagnostic checks:

• 
  
  
  • At ignition on, engine not running, the BARO Sensor and four MAP/Pressure Sensor input signals are compared. If one of the MAP/Pressure Sensor input signals has a difference of more than a calibrated threshold from the others, a performance fault is set against that sensor.
  • With the engine running, the input signals of the three MAP/Pressure Sensors that are downstream of the Supercharger Inlet Pressure Sensor (Supercharger Outlet Pressure Sensor, Bank 1 MAP, Bank 2 MAP) are compared. If one of the sensor input signals has more than a 10.0 kPa (1.5 psi) difference from the other two, a performance fault is set against that sensor.

BARO/Supercharger Inlet Pressure Sensor rationality diagnostic check:

• The Supercharger Inlet Pressure Sensor signal is compared to the BARO signal to check rationality of the sensors. During natural aspiration, the Supercharger Inlet Pressure Sensor signal cannot be greater than the BARO signal plus 10.3 kPa (1.49 psi). During boost conditions, the Supercharger Inlet Pressure Sensor signal and BARO signal pressures should be similar. If the diagnostic fails during a drive cycle, a fault is set (P0069) and the secondary Supercharger Inlet Pressure Sensor rationality diagnostic is run to determine which sensor is irrational.

MAF/Supercharger Inlet Pressure Sensor rationality diagnostic check:

• 
  
  
  • This diagnostic runs continuously, unless any airflow, throttle, MAF, BARO, or Supercharger Inlet Pressure Sensor diagnostics have failed. Then using the pressure differential across the throttle opening (BARO - Supercharger Inlet Pressure Sensor), the PCM models the mass air flow volume through the Throttle Body. This modeled value is compared to the actual MAF Sensor signal input to the PCM. If the difference is greater than a calibrated threshold, a fault is set (P1613) and the secondary Supercharger Inlet Pressure Sensor rationality diagnostic is run to determine which sensor is irrational.

Supercharger Inlet Pressure Sensor rationality diagnostic check:

• If either of the first two diagnostics fail during a given trip, or if one of the downstream MAP/Pressure Sensors is determined to be irrational, the PCM runs a secondary diagnostic to determine if the Supercharger Inlet Pressure Sensor is rational. With the engine in a natural aspiration condition (not boosted), the PCM compares the signal input from the Supercharger Inlet Pressure Sensor to the signal inputs from the Supercharger Outlet Pressure Sensor, Bank 1 MAP, and Bank 2 MAP Sensors. If the Supercharger Inlet Pressure Sensor is not within a calibrated threshold of the other three MAP/Pressure Sensors, it is determined to be irrational and a fault is set (P121B).

Temperature sensor rationality checks:

• 
  
  
  • After a cold soak of the engine, the Engine Coolant Temperature (ECT) and Ambient Air Temperature (AAT) Sensor inputs are compared to the inputs form each of the temperature sensors located in the MAF and MAP Sensors. If a temperature sensor is not within a calibrated threshold of the ECT or AAT Sensors, a performance fault is set.

• This diagnostic runs continuously with the engine running.

Set Conditions:

  • During natural aspiration operation the Supercharger Inlet Pressure Sensor reading is greater that the BARO reading plus 10.3 kPa (1.49 psi), or during boost operation the Supercharger Inlet Pressure Sensor is not within 15 kPa (2.18 psi) of the BARO reading.

Default Actions:

• The MIL light will illuminate.
• Boost is disabled.

Wow, that was a bit above my technical ability. Do you have a cliff notes version? Lol. Thank you for the info! I am going to bring that in with me tomorrow when I have my service department look it over. Dr. Buick, the check engine light was off just a minute ago when I went to the store. But the code was saved in diagnostics.

DO NOT take that in with you Please.I will not be posting anymore of those than.

 

[CO Springs Sublime Kitty]

Ok. You got it. I will keep that to myself. I was just trying to decipher all of that. From what I gather, the code was thrown because the Supercharger Inlet Pressure and the BARO were out of sync. That's about as far as my understanding was able to take me.

thanks, I would say yes out of sync if light is off

 

[CO Springs Sublime Kitty]

Is there a fix for that at home, or is that something a shop will have to recalibrate? And I will accredit google for my little bit of knowledge if asked.

 

[281]

If It was me I would not worry till it happens again. Its a stored code not active so all dealer will do is clear it No problem found and give you back your car

 

[CO Springs Sublime Kitty]

Ok. Thanks for all of the help!
