Citroen C3 1.4 MAF

Post by raymondoD »

This is a 2004 UK car imported into France
The EML light has been coming on, at first erratic stayed off for 2-3 weeks, more recently permanently on. I have replaced the MAF sensor 3 times, always throws up code P0102

All visual check seem fine, no water in ECU connectors or crusty connexions. No apparent damage on cable and connector.

What should the voltages be on the connector pins. VIN No is VF7**************[VIN obfuscated, can be read by forum staff]

The vehicle failed its Control technique and I was given3 weeks to fix the problem, but so far no good. The EML goes out as it should when starting if I disconnect the MAF connector. So I figure it is some some problem from the MAF.

HELP

Welcome along

Have you got diagnostics that can read live data? I would check the EGR valve - is it moving, and is it tracking the requested position closely? What air flow is the car seeing?
