SOURCE: saturn sl2 emissin problem

If the SES light is on, take a paper clip bend it in a u-shape and jump the scanner input positions A B. This should flash the ses in sequesces to give you the trouble code, Please see the following link. http://www.troublecodes.net/GM/ Refer to the code to see what the issue may be. SES lit means that there is a emmissions related issue. Refer to the other links for additonal information on O2 sensor resistance, and the egr valve solinoid. Check the EGR is relitive easy for operation. Remove the vaccum hose and place a hose of similar suckon the hose to pull vaccum if the diafram underneith retracts, hold the vaccum by plugging off the tube with your touge if the diafram retracts, will not hold the vaccum, it is bad. The solinoid should read 40-60 ohms if good. http://www.saturnfans.com/forums/index.php http://www.aldlcable.com/sc/pages.asp?pageid=21

Emission test failed HC (PPM)


i can be, only 2 things, or both.
1: engine running way too rich.
2: dead cat.
(both happens, too)
replace the cat, might be cheaper that full engine diagnosis and repair.
in a real shop we test the cat. using up and down stream tests.
with the 5 gas analyser.
but the truth is a new CAT can hide a very filthy running motor.

Fail smog test


fist i would like you to post the year make and model of the truck along with the HC ppms and NOX ppm it would be very helpful but high hc and nox can be attributed to a faulty EGR system nox is produced when the combustion chamber temperature gets too high so a small amount of exhaust is cycled back into the air stream to help cool them there are other causes but without looking at the levels its much harder to say

I have a 93' Ford Taurus that failed emissions


run the fault codes to find the faulty sensor
sensors that control the exhaust emissions are the HO2S ( heated oxygen sensors in the exhaust manifold/s
the O2 sensor ( oxygen sensors after the cat converters ) and the EGR unit that recycles exhaust gas back through the engine to re-burn the gasses
