| P2073 MAP Sensor Signal Higher Than Expected |
DTC (PGM-FI)
- Vacuum leak check:
Check for vacuum leaks in these parts:
- PCV valve
- PCV hose
- EVAP canister purge valve
- Throttle body
- Intake manifold
Are there any vacuum leaks?
YES
Repair or replace the parts with vacuum or air leaks.
NO
Go to step 2.
- MAP sensor performance check
-1. Start the engine.
-2. Hold the engine speed at 3, 000 rpm without load (CVT in P or N, M/T in neutral) until the radiator fan comes on, then let it idle.
-3. Check the parameter (s) below with the HDS for 5 seconds.
Signal Threshold Current conditions Values Unit Values Unit MAP Sensor More than 53.3 kPa More than 400.0 mmHg Did the value maintain the malfunction threshold for 5 seconds or more?
YES
NO
Go to step 3.
- Problem verification
-1. Clear the DTC with the HDS.
-2. Test-drive the vehicle under these conditions:
- Engine coolant temperature (ECT SENSOR 1) above 158 deg. F (70 deg. C)
- Engine speed between 1, 400-6, 700 rpm
- Transmission in D
- Drive at a steady speed between 55-75 mph (90-120 km/h) for 10 seconds, then decelerate (with the throttle fully closed) for 2 seconds or more
Signal Current conditions Values Unit ECT SENSOR 1 ENGINE SPEED VEHICLE SPEED -3. 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 3-2 and recheck.
