More likely a bad pcv hose from the intake. They collapse and leak. Check while engine is running, they **** shut and leak.

OBD test - Emissions test


hi ecudave, i will go for a tune-up / clean up; the injection system, intake and replacing the sparks, regular maintenance like this will surely clean you emmision. as per re[air cost or shop costs, that will still depend on which part to clean or to work on or even to replace like the spark, but it will not be more than $400.

hope that helps

My 2000 Chevy Malibu won't pass smog because my secondary air systems not ready , any clue?


Yes . GM has had problems with Secondary Air Injection System ! Should have stored DTC - diagnostic trouble code . There is a electric fan motor that pumps air into the exhaust when cold . These systems get water into it causing problems ,an the diverter valve can develop problems as well . I will send a link for a video on testing the system ! Here is a description of the system .
The Secondary Air Injection System (AIR) aids in the reduction of hydrocarbon emissions. During open-loop fuel control, air is injected into the exhaust stream for a specified amount of time. Heat generated from post-combustion oxidation helps the catalytic converter reach operating temperature sooner (referred to as converter lamp off). The following conditions determine pump operation:
?€¢
Start up ECT and IAT must be more than 4.4°C (39.92°F) but less than 30\°C (86°F).

?€¢
Start up BARO must be more than 75 kPa.

?€¢
The start up conditions will operate for 70 seconds or till the vehicle reaches Closed Loop.

Were is the fuse located on a 02 linclon ls for the secondary airflow injector


The solid state relay (Figure 124) switches the high current required for operation of the electric AIR pump. Input control to the solid state relay comes from the powertrain control module (PCM).

Not sure of the cost but most states have a clause that states if you you spend X amount of money trying to fix the problem they will give you an overide until next year for inspection. This will give you time to get it fixed. Call your state dmv office for these details. Good luck. I've been in this situation before.

well if you get it scanned again, and you get a lean bank 1 and 2 code then you may have a intake manifold gasket thats leaking. I just worked on a van that had them codes. and I ended up changing the intake manifold gaskets to get it to pass the emissions test for inspection, I live in new york state, po171 and p0174 are the lean codes. we did the maf sensor, new 02 sensors, egr valve and still got this lean code. good-day and god blessyou. it was on a 99 ford windstar van.

That noise is the secondary air pump (an emissions device) and it appears to be failing. If you have emissions checks in your state inspection, when it fails completely you'll end up with two codes and a check engine light and will not pass inspection. I assume you hear this only on cold start, correct? If so, then it's your secondary air pump.

Your gas mileage will suffer and if your state requires an annual emission inspection, you will not pass. There is also a possibility that your catalytic converter's life will be shortened because of improper combustion. Ask the dealer if these component are covered under the emissions warranty.

Mass Air Flow sensor! Just remove your air filter cover. Go to Auto Zone and purchase some solvent. Spray past the air filter and it should correct the problem. If not, replace the Mass air-flow sensor. This is commonly mistaken for an oxygen sensor. Mine did this and I followed these steps and it fixed the light. BTW, the light stayed on for 5 years before I fixed it. Never hurt anything. It's normally something to do with emissions. Dummy lights. :)
