OBD STATUS
P2074 MAP Sensor Signal Lower Than Expected
Does the HDS indicate FAILED?
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.?
