A P006A trouble code is related to a vehicle’s mass air flow or mass air pressure sensor that monitors the incoming air into the intake manifold.
P006A is an OBD-II generic code for a signal correlation problem between the engine computer and the mass air-flow (MAF) or mass air pressure (MAP) sensor in that the reading coming from the sensor is not within the manufacturer’s parameters.
The most common causes for a P006A are:
Symptoms will vary between vehicle, with some drivers reporting no noticeable issues other than a check engine light. Other vehicles will experience power loss, surging and audible fluttering.
Because of a number of known cases of aftermarket cold air intake systems causing P006A codes, your mechanic will first inspect the engine for any modifications. It’s highly recommended to remove aftermarket parts, reinstall the OEM parts, clear the code, reset the engine computer, and test drive the vehicle for the code’s return.
If there are no aftermarket parts, your mechanic will test the MAF or MAP sensor for contamination, cleaning as necessary, before testing for continuity. If the sensor is deemed faulty, it will be replaced and the code will be cleared.
Aftermarket intake systems can cause P006As, making it important to check for these before moving on to replacing other parts.
A P006A isn’t a particularly serious code, but it can cause poor driving characteristics on certain vehicles.
The most common repairs for a P006A are as follows:
While rare, replacing the engine computer may be a needed repair as well.
P006A codes are common in turbocharged Ford models, both with gasoline and diesel engines. In fact, Ford released a service bulletin for 2003 and earlier 6.0 liter powerstroke trucks and some later model, four cylinder EcoBoost models have also been affected.
