Moin, I have read out the following permanate error codes. After the deletion, the again… MKL does not light up. ECM-1200 intake air temperature sensor. Signal too high / signal too low ECM-170F air pressure sensor/charge pressure sensor – range check / wrong signal ECM-1600 charging pressure sensor. Signal too high / signal too low Have a little Googleled around, on an English-language volvo forum the last two errors occurred with someone. the culprit is supposed to be a “MAP sensor”. Does this sensor also have a different designation and where is it located ? what looks like with the intake air temperature sensor … a follow-up error from the map sensor ? and benefits, if something like that does not have to light up the MKL ?
