Help...Limp Mode!

mendez · 05-13-2013, 09:19 AM

I had an Increased Emissions a long time ago, after replacing fuel cap and DMTL pump the error came back. I took it to the dealer and they told me the Vent Valve (Purge Vale) was bad and my Thermostat was open.

So, I decided to do the labor myself.

To solve the "Increased Emissions" I changed the Vent Valve and I replaced the thermostat to solve the error code# 2B59 (for the thermostat open error). I way I refill the radiator with coolant could cause the thermostat error to show up?

So, after I replaced the Vent Valve and Thermostat this past Saturday. I turned the engine on and the car seems to run well, I did not drive it until this morning!.

After driving aprox 1mile drive, I got the check engine light and went to Limp Mode.

My car did not have any Throttle Actuator symptoms, but it looks like I need to replace it!!!

Could it be that I did not install the Air Manifold correctly? or If I did not disconnect the battery when I change the thermostat and vent valve??

I'm starting to get frustrated with this car guys......

Any help will be great!

Jose

Had the exact same errors, throttle actuators were replaced last year under warranty, car has been running strong since.

Thanks for your quick reply. I think I have a leak , a "T-Fitting Leak"... Maybe I did not apply alot of preassure to isntall the Air Manifold.....

I agree that it could be the throttle actuator problem. It seems to be popping up frequently especially on 2008 model cars. My passenger side one failed a couple of weeks ago. Still waiting on a replacement part.

I can check the fittings and clear the code....Drive one mile and if the error shows back, it has to be the Throttle Actuator...which I can't believe it is.....What a coincidence that I replaced two parts and a mile later I need to replace the T.Actuators...

Quick Update....I re-install the air manifold, clear the ecu and I was able to drive the car. No codes came up....I have my fingers crossed just in case!
