Default Fuel economy & engine management light

Hey guys,

So I've owned my 2004 Carry for a couple months now.

The EML has been on ever since I bought it. The previous owner said it was because of the o2 sensor, and that it was a known fault with the ECU software. He said it sometimes goes out but hasn't happened yet

It drives absolutely fine, so I am reluctant to do anything about it just yet. The MOT is due in April so will need to fix it by then. I bought a cheapie code reader off eBay and that reads o2 DTC's but cannot clear them

I imagine the only problem is that it is probably running either lean or rich when engine cold. Had no issues running as I say though.

This brings me onto fuel economy... I am getting just shy of 30mpg... how does that compare with other owners?

Thanks guys!

Hi Andy, think you may be the only Carry owner who comes here from the UK so I assume you have the 1.3 engine. That's the kind of mileage I'd expect to be honest even if it's not very good. Post up the fault code/s so people can advice on remedy. Quirky little vans but a Local chap uses one, buzzing about all day delivering parcels for Amazon. Seems ideal for that as he can park up easily even if he can't load up that much

Whenever you're looking at buying a used car and there is a fault and the PO says <whatever the PO says> - it's safe to assume he's lying - remember he wants to get rid of the car.

If there was a known "fault with the ECU software" that caused a few hundred thousand check engine lights to turn on, Suzuki would have been forced to deal with it.

Find a reader that can read the codes and find out what code(s) has been set, and then you can determine how to proceed, and the codes can be cleared by disconnecting the battery for a few minutes.

It's been a while since I had a Carry (early 90's), but I'd say 30 mpg is good, if we're talking about UK gallons.

Hi Darrell, yes it is the 1.3 engine

I can't remember the exact DTC now, but it was definitely to do with the o2 sensor.

Fordem, I appreciate what you are saying but the previous owner seemed very sincere, and since the DTC does match what he says, I am inclined to believe him.

I have googled the DTC and the Carry and have found a number of pages/threads that support what he said about it being a common Carry fault.

I have tried disconnecting the battery to clear the code but that sadly didn't work

That would indicate that you have a HARD fault.. You now have a choice,

Either:
  • throw a part at it and hope you have it right, or
  • Diagnose the problem properly..
