7 年日本车, low mileage.
No ppm: limit = 0578; reading= 1282
两年以前，同样的原因 FAIL。结果在Canadian Tire换了Oxygen sensors， 过了 emission test。刚过两年，又出现同样问题。check engine 指示灯亮的。
Canadian Tire要$165检查后才能给出具体故障，真坑人，要知道两年以前，我就在同一家Canadian Tire换的Oxygen sensors。$700只保了两年！
不知哪位能给出出主意。
网上查了一下：
Failed Smog Check Emissions Test California Nissan 300zx CO(PPM) VIR
These are the possible problems:
bad o2 sensor
bag EGR valve
bad cat
bad timing
dirty injectors
Car failed No PPM smog? - Yahoo! Answers
These are the possible problems:
bad o2 sensor
bad EGR valve
bad cat
bad timing
dirty injectors
bad plugs or wires
the less costly fixes include replacement of the o2 sensor and EGR valve i would not clean the EGR I would buy a new one there are very cheap you can pick these up at any local parts store .
also run some injector cleaner through your car at least a full tank of gas and one bottle of injector cleaner should be ran through.
you can also have your timing checked for a relatively low price.
and when you go into to have the vehicle checked make sure the car is been running because your cat convertor has to be warm in order to preform at it peak so do not do it when the car is cold.
all of the above are pretty reasonable fixes the general rule of thumb when you work on your own vehicle is start with the cheapest fix first then go on to the next.
