2009 Ducato 2.3 – No throttle response (intermittent)
I’ve owned a2009 (09 plate) 2.3 Ducato Motorhome for 3 years, its done 30,000 miles in total, and has been regularly serviced.
I recently drove it to Southern France for a holiday, and one day when I started the engine, it would only tick over and wouldn’t ‘rev up’ at all.
The accelerator pedal felt normal, and was operating up and down freely as usual, but the engine just wasn’t responding?
After about an hour of head scratching, and trying repeated starts there was no change, so I called for breakdown assistance.
The fault couldn’t be cured on-site, so we were recovered to a French Fiat garage about 20 miles away.
The garage prioritised diagnosing our fault, and the next day they fitted two main (genuine Fiat) parts as follows;
0071724306 Throttlebody/Electrovanne EGR (E.S.) and 0504388760 Cables Assembles’
Their invoice shows two fault codes detected; P0638 and P0402
The van appeared to be performing normally again, so I paid their bill and we headed North towards Calais.
The next morning on start up, the same fault happened again, the van started OK, but had little or no throttle response.
Fortunately,this time the fault rectified itself after around 1 minute, and the engine could then be revved up normally.
As we were by then around 200 miles North of the garage who’d repaired the fault, we decided to continue on to Calais.
We are now back in the UK, and the van has done the same thing on two further occasions, luckily clearing itself both times.
The fault is intermittent (for the moment) but obviously I would like to get it permanently rectified.
Any thoughts on possible causes, and/or suggestions of the best way forward from here?
