meinert Posted February 26 Share Posted February 26 Got a DTC P0069 error and an engine mailfunction warning. Don't know that much about engines but as far as I understand the MAP sensor and the BARO sensor should both be equal atmospheric pressure (100kPa/14,7psi) when engine is off and when engine at idle. And when at full trottle I would expect a value around 250kPa/36,3psi. My BARO shows 14,7 PSI but the MAP shows 35,7 PSI when engine is off? To me it sound like a defect MAP sensor, but before replacing it I would like to hear any relevant input.....is my understanding of the two pressure sensors correct? Any other sensordata that is relevant? Quote Link to comment Share on other sites More sharing options...
meinert Posted February 27 Author Share Posted February 27 Just checked a few other sensordata when driving: - Boost show 21,03 PSI constant under different loads - EGR: 100% - EGR Err 99-100% I am using a china ODB2 adapter and Torque Pro for the readout.

TomsFocus Posted February 27 Share Posted February 27 The EGR may not operate correctly while there's a MAP sensor fault. There's no BARO sensor on these. It's a calculation from the MAF sensor. It looks like you have a faulty MAP sensor - personally, I would change that based on the diagnostics that you've already done. 1 Quote Link to comment Share on other sites More sharing options...
