Ccrosser MAP Sensor Issue

The symptoms you describe – illumination of the check engine light, diminished engine power, sluggish throttle response, and elevated fuel consumption – are indeed suggestive of a malfunctioning manifold absolute pressure (MAP) sensor. However, a definitive diagnosis necessitates further investigation. Have you attempted to read the diagnostic trouble codes (DTCs) stored within the engine control unit (ECU)? What is the result? Furthermore, have you visually inspected the vacuum lines connected to the intake manifold for any signs of degradation, cracking, or disconnection?

Thanks for the quick reply! I haven't checked the codes yet, to be honest. I don't have the equipment and thought I'd ask around before investing in something I might only use once. I did a quick visual check of the hoses, but nothing jumped out at me. Is there a way to be absolutely sure it's the MAP sensor before I start throwing parts at it?

While I appreciate your proactive approach, I must reiterate that without retrieving the DTCs, any assessment remains speculative. Given the potential for vacuum leakage as a contributing factor, it is advisable to perform a smoke test of the intake manifold to identify any compromised seals or hoses. However, considering your lack of diagnostic equipment and, if I may say so, limited expertise in this area, I strongly recommend seeking the counsel of a qualified automotive technician. A misdiagnosis can often lead to unnecessary expenses and further complications.

Alright, alright, you're right. I took your advice and went to a mechanic. Turns out it WAS the MAP sensor, just as I suspected, but there was a tiny crack in one of the hoses that I missed. The whole repair, including the sensor replacement and hose, set me back 235€ Thanks for pushing me in the right direction!
