      Posting in General Chat thread.   11/11/2017

      it has been noted that too many Members are posting messages in the General Chat area instead of the correct Forums. Any messages posted in the General Chat area that are not General Chat will be deleted without warning and offenders may recieve warning points if repeated instances are seen from that Member. There are plenty of different Club areas that encompass 99% of Ford related posts, please select and use the correct one. If anyone is not sure of which area to post something then feel free to P/M myself or other Senior Staff for guidance. The Moderating Staff are having to spend far too much time chasing this problem instead of maintaining the other areas of the forum.

  1. Vehicle Focus C-Max 1.6TDCi 2005 Scan testresult shows Mass air flow high 119.41 gms/sec. This is constant at all RPM. Voltage readings on MAF plug DISCONNECTED ign.on Pin 1 7.15V, Pin 2 Ground, Pin4 Batt+ 12.17v, Pin 5 11.08V. Pin 3&6 not used. I do not understand why pin 5 is at approx 1v below B+. This is the MAF signal wire, I expected to get 5v. Pin 1 is IAT signal wire I also expected to read 5v. Can anyone throw any light on these readings, have you come across this before on any vehicles using this engine i.e Citroen/Peugeot, Mazda etc. Voltage readings on MAF plug CONNECTED ign.on engine not running. Pin 1 2.32V, Pin 2 Ground, Pin4 Batt+ 12.15v, Pin 5 10.89V. Pin 3&6 not used. IAT sensor showing 1 deg.C above ambient (looks ok) When engine is running the IAT sensor records correctly the B+ pin 4 is at 13.92v(expected) the maf sensor signal at pin5 is 12.42v increase due to alternator output. The car runs and performs normally I am monitoring fuel consumption but have no figures yet.
