DTC P2074  : MAP Sensor Signal Lower Than Expected

DTC (PGM-FI)

1. MAP sensor performance check

   -1. Turn the vehicle to the ON mode.

   -2. Check the parameter(s) below with the HDS.

   Signal	Threshold		Current conditions
   	Values	Unit	Values	Unit
   MAP SENSOR	Less than 53.9	kPa
   	Less than 404.5	mmHg

   Did the value maintain the malfunction threshold for 5 seconds or more?

   YES 

   Replace the MAP sensor .

   NO 

   Go to step 2.

2. Problem verification

   -1. Clear the DTC with the HDS.

   -2. Start the engine. Hold the engine speed at 3000 RPM without load (in P or N) until the radiator fan comes on, then let it idle.

   -3. Test-drive under these conditions:

   • Engine coolant temperature (ECT SENSOR 1) above 158 deg.F (70 deg.C)
   • Engine speed at 1100 RPM or more
   • Transmission in D
   • Drive at a steady speed at 15 mph (24 km/h) for 5 seconds or more with under half throttle

   DTC Description	OBD STATUS
   P2074 MAP Sensor Signal Lower 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 freeze data/on-board snapshot of this DTC is recorded, try to reproduce the failure under the same conditions with the freeze data/on-board snapshot. If the HDS indicates NOT COMPLETED, go to step 2-2 and recheck.
