Bellashanna81 Posted November 24, 2015 Posted November 24, 2015 Hi!, I wonder if someone can help please. I have a 03 plate 1.6 Zsara Picasso, Its done 83k mileage. Firstly, on Sunday, I had been shopping, returned to my car & it wouldn't start. It wouldn't turn over, there was no noise whatsoever. Called the AA who came out, they connected their battery pack & it started straight away. I started to drive home after a while, and a few miles up the road, the engine management light came on, it displayed 'Engine Fault' and the engine cut out completely, as well as the power steering & everything. I pulled over & called the same guy from the AA on his mobile. He came 5 minutes later. The car then started up again, but with the engine light still on, he followed me to my parents house - It was half a mile away - and we pulled up so he could look. Nothing came up on his diagnostics machine thing, apart from something to do with the CO2 emissions sensor. He said that wouldn't have anything to do with the engine cutting out. He suggested i take it to the garage. The next day the garage looked at it, they said it needed a new battery as 3 of the 4 cells weren't working. They replaced it & I drove it fine back to my parents house (a mile away from the garage). It started each time fine & no engine light, so yesterday evening I went to go home (30 miles away). About 4 miles down the A47, the same thing happened again. Loss of power, engine fault displayed & Engine light coming on. I luckily was able to coast to a stop in a dirt patch off the main road, otherwise I would have been on a busy A road. The AA sent out a recovery vehicle as a priority - being a woman alone in the dark - and Tears recovery came. I was able to start the car again & he followed me to the Shell garage 1 mile away so he could look at it.He plugged it in to the computer & it displayed several error codes, They said something like 'Cylinder 1 injection low', 'Cylinder 2 injection low' and the same for 3 & 4, and then the same CO2 emissions as the previous day, He fiddled under the bonnet & said he had discovered the fault, it was the wiring harness that goes to the injectors, it needed replacing. He said it would have affected the CO2 emissions somehow (he did explain but I was in such a state with being on my own late at night and in the freezing cold - i didn't really take in what he said about that) He said that it was common & being a mechanic for over 20 years, he had seen it many times before.He said a garage would need to order the part from main dealer & would take a couple of days to arrive but only 20 minutes to replace. Anyway, i managed to get home (whatever he did under the bonnet enabled me to drive back to my parents where i'd just come from) My dad has taken it to his local garage today. I am so worried about this - i have a 2 year old daughter, and I was lucky she wasn't in the car with me at the time, it would have been awful. Is this something anyone on here has experienced before with being a problem & had it changed, with no further issues?Sorry for the essay, I need some reassurance, as I have been Googling it and can't seem to find the answer!Thanks in advance.

paul.h Posted November 24, 2015 Posted November 24, 2015 Welcome to the forum. If there is damage to the wiring then it is most likely the fault. We had a 2.0 hdi Picasso and I remember seeing the engine plastic cover was rubbing on some wiring at the right side (looking from the front of the car) near the back so I cut part of the cover off to stop this - so maybe this can also happen on the petrol cars. I think the CO2 sensor you mention will be the exhaust O2 lambda sensors. There are 2 on the exhaust, one on the catalyst inlet and one on the catalyst outlet. The first adjusts the fuel flow so emissions are low and the second checks the catalyst is working. The second would not affect running but the first would put the car in limp mode and limit performance. Both would put the engine management light on. Quote
coastline taxis Posted November 24, 2015 Posted November 24, 2015 sound like the wiring loom to your injectors and sending wrong/intermitent /none information to the injectors. it will cause the cylinders to run lean/rich which the o2 sensor will pick up and try to alter the fuel being injected into the engine. it cant do it as the wiring loom wont alow it so on comes the engine light. I thinkthe battery was a unrelated fault and the recent cold snap has probally killed it off. The last one we done was around £60 for the new section off wiring plus the labour. once replaced the car will be fine Quote
Bellashanna81 Posted November 30, 2015 Author Posted November 30, 2015 Thanks to you both - the garage replaced the wiring loom harness for the fuel injectors & it broke down again yesterday - thankfully was outside my parents house.When the garage did the work (which they haven't charged for as yet) the mechanic said it was either the wiring loom harness faulty, or could be the computer reading the fault. As the harness hasn't fixed it, its now back with them for the alternative,Over a week with no car now & costs mounting up on a hire car as live in the Fens to buses are not regular!! Quote
coastline taxis Posted November 30, 2015 Posted November 30, 2015 can u get a printout of the codes Quote
