P1297 Jeep - No Change In MAP Sensor Voltage
- Restricted MAP Sensor
- MAP Sensor harness is open or shorted
- MAP Sensor circuit poor electrical connection
- Faulty ECM
The Engine Control Module (ECM) detected no change in MAP sensor voltage. Too small difference is seen between Barometric Pressure with ignition ON (Engine Running) an the manifold vacuum for more than 8.80 seconds.
