What causes the p2074 OBD-II trouble code?
P2074 is an OBD-II generic code for the Engine Control Module (ECM) detecting a final mass airflow adaption stored value at a higher load (more than 15% above or below the calibrated threshold). What causes the P2074 code? Leaks or restriction in the air charge cooler or intake air hoses Leaks or restrictions in the crankcase vent system
What does the code p2074 on an ECM mean?
Code P2074 is an indication that the ECM cannot detect how much air is getting into the engine, or the system has restrictions in the intake air supply that restricts the air when compared to the amount of throttle that is opening.
What is the DTC code for charge air cooler?
This generic powertrain diagnostic trouble code (DTC) typically applies to all OBD-II vehicles equipped with a charge air cooler. That may include but is not limited to vehicles from Ford, Chevy, Mazda, Toyota, etc.
When is charge air cooler pump control circuit open?
Code P023A Charge Air Cooler Coolant Pump Control Circuit Open is active when there is an open circuit within the charge air cooler coolant pump and/or its circuit What is the severity of this DTC? Severity in this case would be low. In most cases, this fault will not present any immediate safety concerns.

What causes a p023a coolant pump control circuit to open?
Causes for this code may include: Internal mechanical obstruction in coolant pump Open within coolant pump control circuit Broken or damaged Coolant pump wiring harness Pin/connector problem. (e.g. corrosion, broken lock tab, etc.) What are some P023A troubleshooting steps? Be sure to check for technical service bulletins (TSBs) for your vehicle.
How to test the charge air cooler control circuit?
Measure and record the integrity of the charge air cooler control circuit. Equipped with a multimeter and the appropriate wiring harness, you may be able to independently test the control circuit. This may involve disconnecting the connector at the ECM (Engine Control Module) and the other end at the coolant pump.
