Fault code p2074 - Grand Cherokee Jeep Cars & Trucks

I would say because your fault code indicates "Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Higher Load" you have an air leak in a vacuum pipe.

P2074-MAP/TPS CORRELLATION - HIGH AIRFLOW/VACUUM LEAK DETECTED

Codes translate as...
P2074 = Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Higher Load.
P2047 = Reductant Injection Valve Circuit/Open Bank 1 Unit 1 The first is the air intake system and the second is the fuel delivery system.

there is a service bulletin for this code, try googling chrysler tsb#18-042-04 to see if your symptoms match,could need the computer reprogrammed.

You should check out www.reliable-store.com they have info on repair, service, wiring diagram, electrical diagram, fuse diagram, torque specs, troubleshooting, PCV, gear box, owner's/service/repair/parts manual, .fault codes, error codes, etc everything on all vehicles. must check it out

Trouble code P2074 means: Manifold Absolute Pressure/Mass Air Flow - Throttle Position Correlation at Higher Load

PO0108---Map sensor high
P2074---Mainifold pressure/throttle position correlation-high flow/vacuum leak

A P2074 DTC is the Manifold Absolute Pressure/Mass Air Flow-Throttle Position Correlation at Higher Load. I wuold start with this one first because it came up first and there may be more than one problem.Good Luck.

Are you sure its P2074. only asking because IM having a hard time finding it. If it was P0274 that would of been a injector issue(high voltage) on cyl. #5. if i find anything else I'll contact you.

P2074-manifold Pressure/throttle Position Correlation

CORRELATION - HIGH FLOW/VACUUM LEAK

When Monitored: Engine Running, during all drive modes.
Set Condition: If vacuum drops below 1.5 Hg with engine RPM greater than 2000 RPM
at closed throttle.
