This is my first REAL post and not a response.

Go easy.

I have been dealing w a CEL issue that correlates to "charge air cooler inefficiency" This points to the MAP or 'boost sensor' failure. I removed the map sensor and cleaned it up a bit w some electrical cleaning solvent.

Reinstalled the sensor and the car threw no codes for a day, and now they are back. I've a new MAP sensor on order, but I'm curious if anyone else has experienced this yet. (my car is essentially a 2013).

Thanks for reading.

 

What was the actual DTC code?

Sorry for the late reply, the DTC is P026A.

Found this:

When your car's 'P026A Check Engine' light comes on, it's usually accompanied by a sinking feeling in the pit of your stomach. The light could mean a costly problem, like a bad catalytic converter, or it could be something minor, like a loose gas cap. But in many cases, it means at minimum that you'll be visiting the car dealer to locate the malfunction and get the light turned off.

P026A Code Meaning :

P 0 2 6 a OBD-II Diagnostic Powertrain (P) Trouble Code For Engine Intake Valve Control Solenoid Circuit Low Ambient Air Temperature Sensor Circuit Low Injection Pump Fuel Metering Control 'A' High (Cam/Rotor/Injector)The poor running symptoms are consistent with a MAP sensor malfunction. In addition, in some cases, a bad MAP sensor will not throw a code. Again, the ELD code likely represents a separate wiring issue.

Reason For P026A Code

The reason of P026A OBD-II Engine Trouble Code is Ambient Air Temperature Sensor Circuit Low.P026A DTC reports a sensor fault, replacement of the sensor is unlikely to resolve the underlying problem. The fault is most likely to be caused by the systems that the sensor is monitoring, but might even be caused by the wiring to the sensor itself.

Looks like a trip to the dealer.
