Take your vehicle to a shop and get the codes read.Most do it for free and only takes 10 minutes.This will tell you what is wrong with your emission system.

No power on dash,radio,parking lights and plug for emission test


Check the fuses against a dark piece of paper. I have had some look OK but looking closer against a dark background showed a crack. I had a Toyota that thought it didn't have any gas and would run intermittently. Checked all sorts of things and it was a 15 cent fuse.

Fuel Emissions light that appears on the dash intermittently.


The fuel emission light operates from several sensor that if one is out of parameters tells the CPU that the air fuel ratio is incorrect and so the light comes on. IT may be a MAP/MAF/VAF sensor or a ambient air temperature sensor that is not reporting correctly. Have the fault codes read and see what has been recorded and work from there. The engine will operate alright but there may be a slight decrease in economy that you would not notice unless you record the fuel consumption manually.

Peugeot boxer van 2007 changed interior light bulb blew fuse, renewed fuse, lights worked, but emissions lights on dash board came on and won't go out. Help


Try reading the OBDII with a code reader and see what it is then erase codes and see if it stays off ,could be more than one circuit on this fuse so the fuse blowing has thrown the light on for whatever reason ,Also try disconnecting the battery just out of interest for a few minutes and reconnect it might go out if your lucky

Replace the gas cap and then either ask the auto zone to reset the computer again or disconnect the negative battery cable from the battery for 1 min then reconnect it.

I have an emission system light on my dash. what should i ck. first?


I hope you have read your owners manual,which no one seems to have,and know why different lights come on the dash!
Iam guessing you know that, as soon as a light comes on,that a fault has been detected. Most people could care less.
You have to plug a code reader or scanner into the connector under the dash,below your ign key.
Give me the code and I'll help you out.
I have a 2004 LS and $600.00 worth of manuals and wiring diagrams,Emissions also.
