DTC P2073  : MAP Sensor Signal Higher Than Expected

NOTE: 

• Before you troubleshoot, review the general troubleshooting information .
• Before you begin, check for poor connections or a blockage at the intake air duct.

DTC (PGM-FI)

1. Vacuum leak check:

   Check for vacuum leaks in these parts:

   • PCV valve
   • PCV hose
   • EVAP canister purge valve
   • Throttle body
   • Intake manifold
   • All parts through the turbocharger joint to the throttle body

   Are there any vacuum leaks?

   YES 

   Repair or replace the parts with vacuum or air leaks.

   NO 

   Go to step 2.

2. MAP sensor performance check 1

   -1. Turn the vehicle to the ON mode.

   -2. Compare the value of the parameter (s) below with the HDS.

   Signal	Current conditions
   	Values	Unit
   MAP Sensor (Hi Res)
   TC Boost Pressure

   Does the vehicle differ more than 26.7 kPa (7.9 inHg, 200 mmHg)?

   YES 

   Replace the MAP sensor .

   NO 

   Go to step 3.

3. MAP sensor performance check 2

   -1. Note the value of MAP Sensor in the DATA LIST with the HDS.

   Signal	Current conditions
   	Values	Unit
   MAP Sensor (Hi Res)

   -2. Start the engine and let it idle.

   -3. Check the MAP Sensor in the DATA LIST with the HDS.

   Signal	Current conditions
   	Values	Unit
   MAP Sensor (Hi Res)

   Does the MAP Sensor change 0.67 kPa (0.2 inHg, 5 mmHg) or more?

   YES 

   Go to step 4.

   NO 

   Replace the MAP sensor .

4. Problem verification

   -1. Clear the DTC with the HDS.

   -2. Start the engine. Hold the engine speed at 3, 000 rpm without load (in P or N) until the radiator fan comes on.

   -3. Test-drive the vehicle under these conditions:

   • Engine speed between 1, 700 rpm or more
   • Transmission in D
   • REL TP SENSOR above 42.2 deg
   • Drive 5 seconds or more

   	Values	Unit
   Engine Speed
   REL TP Sensor

   -4. Monitor the OBD STATUS for DTC P2073 in the DTCs MENU with the HDS.

   DTC Description	OBD STATUS
   P2073 MAP Sensor Signal Higher Than Expected

   Does the HDS indicate FAILED?

   YES 

   The failure is duplicated. Replace the MAP sensor .

   NO 

   If the HDS indicates PASSED, intermittent failure, the system is OK at this time. Check for poor connections or loose terminals at the MAP sensor and the PCM. If the on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the on-board snapshot . If the HDS indicates NOT COMPLETED, go to step 4-3 and recheck.
