Hello, Can anyone point me in the right direction for a garage near Reading that can look at my Copen? I've taken it to my local garage but their diagnostics don't seem to be any use and they don't know the model. Thanks, Gareth
The nearest on the Daihatsu website is 20 miles away unfortunately and I don't fancy driving it there with the engine light on. I've been told that Littlewick Green, near Maidenhead are ex Daihatsu so I'm waiting for a call back from them.
Has it only just come on ? As long as the oil and coolant levels are correct, and it’s not stinking of unburnt fuel, I wouldn’t be concerned at a 20 mile drive. Had you just refuelled when the light came on by any chance ?
No, I'd used about quarter of a tank and I had another hours drive or so down the motorway to get home. Drives fine but sounds a little louder than usual. Checked the codes and it says rear 02 sensor.
Ok, well not too devastating then. I only asked about refuelling as sometimes a cross threaded or loose fuel cap can trigger the EML.
Basically any shop can replace a broken o2 sensor, no need to drive 20 miles. Apart from that, a broken rear o2 sensor is no big issue, it will not break the car after 20 miles
Well it's either broken, or giving a reading outside of normal boundaries which would indicate a problem with the fuel / oxygen mix. I did check the fuel cap but the light is still on! My local garage said non of their machines could read the diagnostics, hopefully someone can look at it though.
easy to check first check wires to sensor.. If yours exhaust very rosty use antirostspray before try to unscrew it..or try to unscrew it when exhaust get hot. buy an obd reader...Engine light
Chicken and egg since the sensor helps define the mixture. I think the age of the car means the current OBD2 diagnostics can’t reliably read the codes. Drive to a former Daihatsu dealer - my experience is that they view the Copen with some affection and are more than willing to help.
If it really is the rear o2 sensor (where did you get that information?) then its not a big issue. The rear one does not do anything to the fuel mixture, its purely for emissions purposes (monitoring of catalyst efficiency). If it was the one at the front, I would get it fixed immediately, as the engine has to rely on its "emergency fail-safe program" then. The engine will run, but not efficently, as it cannot dial in the correct air-fuel-mixture.
I read the code with an obd2 reader and it said it was p0136 which the manual says is the rear 02 sensor I think.
p0136 is exactly that. Dont worry, your car will not blow up Just get the wiring to the rear o2 sensor and the sensor itself checked. Every garage can do that for you
Could I get some advice on the situation I've found myself in please? We talked about this being p0136 and I eventually found a garage that ran full diagnostics and replaced the sensor. When I picked it up they said they had to remove the bumper for access which seemed weird but tbh I know nothing so I paid up and left. Then the light came back on, same code. I've taken it back to them again and he's run it again and he says it's the other sensor. He referred to this as the "downstream" sensor, which is the rear one right So I think he's replaced the wrong sensor the first time but he says he remembers it being the other code, and when he checked diagnostics it was all working. How do I handle this with the garage? P0136 couldn't be the code for both sensors right? And he wouldn't need to remove the front bumper to access the rear one?
Both sensors are easy to dismount. Sometimes the rear one . which is behind the catalyst mounted in the exhaustpipe is rosty and need more patience. And he wouldn't need to remove the front bumper to access the rear one? Yepp... It is mounted over no 140 in picture below. Nothing else is to remove, only the sensors OBD-II Trouble Code: P0136 Oxygen O2 Sensor Circuit Low Voltage (Bank1, Sensor2)
1. Probably. If you delete an o2 sensor code it might not come back immediately, depending on how damaged it is. 2. I would not pay for two sensors 3. P0136 is Bank 1 Sensor 2 (the back one), the front one would be P0130 4. I have attached a picture of what you would see if you looked under your car. As you can see its maybe a 15 minute job and no exterior parts need to be removed.
@Sal.. not shinny engine, schon überlegt den mal Glasstrahlen zu lassen? und die Rädchen gehen gar net.. OI BRUV U GOT A TELLY LOICENSE???
There are 2 different typs...post and in front of the catalyst. Different plugs.. Lambda Sensor for DAIHATSU Copen I 0.7 (L880) (68 HP from 2003 )
