Time to closed loop temp too long? (E36 328i) |
|
|
I've started getting the "check engine" light on my '96 E36 328i, and
using a Peake diagnostic took, I've discovered that the "Time to
closed loop temperature is too long". My best guess is that the car
isn't warming up quickly enough, so I've let it idle a bit longer on
cold mornings before driving it. But can anyone tell me what is
causing this? Is there a simple solution, i.e. replace a sensor, or
something?

Perhaps your thermostat is getting a bit lazy? I once had a situation
where the car would warm up more slowly than it used to. Replacing the
thermostat fixed the problem. The part is cheap, and if you have access
to free labor (i.e. your own) it is worth a shot. |

I would guess the error message is in reference to the time for the 02
sensors to go into a closed loop condition. It might mean that the
heater internal to the sensor is not working right. I'm pretty sure
that when the heater fails (is open) a different error is logged. Maybe
the relay that supplies the heater voltage is not working right?

Thank you for the input. I'll check into the thermostat and what it
takes to replace it.

An update: it just got really cold here in sunny New Mexico (we even
got snow)! And so it wasn't long before I realized that indeed, the
thermostat was worn out and stuck open just as you'd suggested. So I
got it replaced and now the "closed loop temp" code appears to be a
thing of the past. Nice when it's something relatively simple...
Thanks again for the input,

Oh that sounds familiar. I used to get that fault on my E36,
also using the Peake tool. The car happened to still be under warranty,
and they fixed it. But, keep in mind that those little Peake tools
are not entirely accurate. I keep getting a fault that says something
cryptic about cylinder 3 or some such. The diagnostic machine at
the Beamer shop I use (much more expensive and sophisticated device) translates
the fault as a minor gas leak, which they still can't find.

Maybe, but I think the O2 closed loop condition begins when it reaches
a preset temperature, as a result of exhaust gasses, which should be
minimally affected by coolant temp. |
