What are the causes of the P2073 code?

Some potential causes of this trouble code may include:

  • The manifold absolute pressure or mass air flow sensor could be faulty.

  • The throttle position sensor could be misaligned or faulty.

  • The wiring or connectors that are associated with the manifold absolute pressure or mass air flow sensors could be damaged.

  • The air filter could be extremely dirty.

  • The powertrain control module could be malfunctioning.

  • A vacuum leak may exist between the air cleaner box and the throttle body.

How does a mechanic diagnose the P2073 code?

A mechanic may begin diagnosing this trouble code by first inspecting the wiring and connectors that are associated with the manifold absolute pressure and mass air flow sensors for damages. Then the mechanic would test the sensors themselves for proper function using the manufacturer’s suggested procedure. Next, the mechanic would check the throttle position sensor for proper function and alignment while ensuring that no vacuum leaks exist and the air filter is clean. Finally, the powertrain control module would be tested. After all of these tests are performed, the mechanic would then relay their findings over to the customer to make a repair decision.

This is a very bad mistake as this code could be caused by something other than either one of these sensors. It is a good idea to make sure your trouble codes get diagnosed by a qualified technician to reduce wasted time and money.
