I have had my 206 cc 2.0 liters petrol engine car for 2 years. I have had a bunch of problems (clutch, rear axle, fan blower motor, thermostate, lambda sensor etc) , repair costs are 4911,90 euros and counting...
Still, a delightful car to drive, even though there are only 2-3 warm months per year for decent cabriolet cruising.
Now I have encountered the trickiest problem so far. I have a camshaft sensor faulty code p0341. Engine light is off. Faulty code can be removed with a scan tool but it pops back right from the second ignition, no matter if the engine is warm or cold. For some reason the first ignition doesn't give any faulty codes.
This wouldn't be a problem, since the engine starts and runs perfectly fine and gives power. Also petrol consumption is normal 8,0 liters per 100 km. But, in Finland there is a mandatory annual checkup for cars older than 3 years (I don't know if you have that in UK?), and they check the OBD-test in the checkup and disqualify the car for any faulty code. Pollution levels are perfectly fine. You can pass the checkup by visiting a car service where they erase faulty codes and make some kind of OBD-testing and write a certificate.
Still, it's a real nuisance and I'm selling the car and a buyer wouldn't appreciate such faulty codes.
The faulty code has been the at least since 2012, as I have heard from the previous owner. 2012 there was a running problem and faulty codes p1335, p0341, p0326, p0300 and timing belt was replaced. Maybe the belt had jumped? Timing was checked again at 2015 when they replaced a lambda sensor because of unevenly running motor.
It is possible that the same code p0341 has been present already since 2011 when the car was imported (originally Italian), because it had been disqualified because of some OBD-code (I don't know which code exactly).
Camshaft sensor was replaced earlier 2015. Now, I took my car to a car electric mechanic who examined it. Camshaft sensor didn't give any signal to ECU. There should be some voltage (5 volts?) from ECU in the signal wire but it was missing. When they gave voltage from an external source to camshaft sensor it woke up and produced normal signal. But without external voltage source, no signal at all. Wiring for ECU to sensor was double-checked. Also plug between edu and wiring was replaced.
Mechanic thought that ECU was broken and it was replaced with a refurbished ECU. Still, the same thing, no voltage in camshaft sensor signal wire. ECU was sent back to refurbishing company where they re-checked it and it should work just fine.
This is where my mechanic surrendered.
So, you have any ideas? May there be a problem with timing belt, it being out a tooth? Problem with crankshaft sensoring? Is the edu in some kind of secondary operating mode where camshaft sensor is disabled?
