Dodge Journey MAP Sensor Failure Hits Performance

Had the same symptoms on my 2014 Dodge Durango last month. The MAP sensor readings were way off, causing poor engine performance and high fuel consumption. A pressure sensor test confirmed major vacuum leakage around the intake manifold gasket. The repair required: Complete MAP sensor replacement, New intake manifold gasket installation, Vacuum line inspection and replacement, ECU recalibration after sensor installation It was a serious issue since bad MAP sensor readings can damage engine components over time due to incorrect fuel mixture. The car runs much better now, restored power, normal fuel consumption, and no check engine light. Would strongly suggest getting it checked soon since continuing to drive with faulty pressure sensor readings can lead to: Further engine performance issues, Potential damage to oxygen sensors, Risk of catalytic converter problems, Increased emissions The symptoms match classic MAP sensor failure. Having the proper diagnostic tests done first will confirm if its the sensor or potentially a vacuum leak issue.

Thanks for the detailed reply about the MAP sensor replacement. Dealing with a very similar situation on my 2011 Journey right now. Getting those exact symptoms you mentioned, poor performance and high fuel usage. Good to know the sensor replacement fixed it completely on your Durango. Just wondering, do you remember roughly how much the total repair cost was? Also, has everything been running smoothly since the automotive sensor replacement, or have you noticed any other issues pop up? Trying to budget for this repair and want to make sure I address everything while its at the shop.

After having the car checked by a certified mechanic, they confirmed it was indeed a faulty manifold pressure sensor causing the problems. The repair addressed the large vacuum leakage issue, costing 235€ total including parts and labor. Since the repair three months ago, the engine performance has been perfect, no check engine lights, fuel consumption back to normal, and the sluggish response completely gone. The intake manifold seals were also inspected during the fix, which helped identify and resolve all vacuum-related issues. The car runs just as good as new now, with all automotive sensors working correctly. Having proper manifold pressure readings has made a huge difference in overall engine operation. No additional problems have surfaced since the repair, confirming it was definitely worth fixing rather than letting it potentially cause more damage. The mechanic did a thorough job testing all connected car sensors to ensure everything was properly calibrated after the repair. This comprehensive approach probably helped prevent any follow-up issues from developing.

Thanks for the input. Went ahead and took my Journey to a certified Dodge mechanic yesterday based on the advice here. Diagnosis confirmed what you all suspected, faulty MAP sensor was the culprit. Total repair came to 290€ which included: New MAP sensor, Installation and testing, System recalibration, Full sensor diagnostic check Already notice a huge difference after the sensor replacement. Engine feels way more responsive, that sluggish acceleration is gone. Fuel gauge is showing better consumption too. Mechanic showed me the old manifold sensor, connection was corroded and readings were all over the place. Said catching it early probably prevented damage to other engine components. Really glad I got this sorted before it caused bigger issues. Car runs like new again. Thanks for helping me avoid another costly misdiagnosis at a unusual shop.
