Thread: 2010 PUMA continually in limp mode

My 110 seems to go into limp mode when ever it is starting from cold or after waiting at lights for any length of time. Usually no engine warning light is coming on, but it did once and got Ward at Graeme Coopers to put the big scanner on which said earth fault at MAP sensor. Cleaned plug and socket but not actual sensor yet with some success but problem has come back. Noticed today that orange wire going into plug has break in the insulation.
I’m thinking the problem is connected to this crap wet weather we’ve been having in Sydney as the problem seems to lessen as the engine bay gets hotter and everything cooks a bit.
In the past I’ve replaced MAF plug with replacement from UK. Reasonably easy splice of new plug onto existing harness. Problem was a corroded wire right where it bends going into plug, terrible design with no strain relief. Anyway, now I have same problem with MAP and it appears the supplier in the UK is no longer supplying due to shortage of components (related to chip shortage I think they meant)
Has anyone been able to find a quality supplier of MAP & MAFs and the plugs that connect to them?

I had a similar problem with the harness to the turbo wastegate actuator, it was installed with tension on one of the wires which fractured and caused repeated limp mode. I went to a wrecker who specialises in ford transit vans, which I'm sure you're aware have the same engine but are far more numerous. I got him to cut the connector I needed out of a loom with as long as possible wire tails left on, then grafted this into my loom in such a way that there was no tension. Problem has not recurred.
