Had my engine replaced in July and never really noticed but my SES light wasnt lighting up when I start it up. So now I went for my emissions test and of course it failed coming up with 0421 lean 1st bank and SES not functioning. My question is how do I go about replacing the bulb? Is it simply taking the cluster apart and changing it out? Will this eliminate the code for the SES? Also are the anti-foulers the best option for the other code or should I just clear it everytime I need an emissions?
Thanks guys!

 

since when do we have emissions testing in wi? ive never had to do it ever so thats why im wondering....

 

Come down to Milwaukee been doing them since I was 16, any ideas???

 

Anyone????????????

 

This must mean that this question has been answered before however I have searched and cannot find the answer could someone point me in the right direction?

 

Changing the bulb is indeed as simple as taking the cluster appart and changing the bulb.

Will it erase the code and fix the problem? No.

A list of mods would help us pinpoint the reason behind the code.
Your thread is not getting much attention because of where it is on the board. If it would have been posted under troubleshooting, your question would have been answered already.

 

When I took it for the test I cleared the catty code but because the CEL is malfunctioning they failed it. I am having trouble getting the cluster out is there a how to on this dis assembly? thanks blaze.

 

According to the header it says to post your questions here. ????

 

It's (I think) a total of 5 screws. Touching the plastic face of the cluster move your hand up. There are 2 screws. One on the left and the other on the right. Pull the black plastic piece out.

Now there are 3 screws left. One at the bottom behind the steering wheel shaft. Just look at the gauge cluster and look down. Make sure your steering wheel is moved all the way down. There are 2 left. One in the top rght and the other in the top left. Take those out. It's not out just yet. There are 2 ribbons you have to pull out as well. They have clips so be careful not to break them.

Once you get that out just find the light bulb over the ses light overlay. but from my experience you have to order that bulb online. Or you could just take the light from the open door symbol and move it down.

 

thx Joge, I also took a look at my bill from the engine replacement and it shows a PCM failed I did do some searching and I know there is some relation to the emissions code I am thinking of calling the dealer I am concerned that they disconnected the CEL??? Any suggestions

 

honestly, if it was replaced by the dealer (pending how long ago) take it back and tell them to make it right or its money out of your pocket later on,

 

^ what he said but for 0421 the de fouler trick is the best way just remember to run it for 100 miles to make sure the ecu completely resets.

 

ok thanks guys
