Question about 1994 Mercury Cougar

1 Answer

Car does not pass the emissions check.

Went to use a diagnostic scanner to see if it detected a problem, but couldn't find the receptacle under the drivers side dash or under the hood. Does it even have one? This car is only driven around 800 miles a year and has always passed the emissions check before now. Readings: IDLE SPEED CO = 6.18%, HIGH SPEED CO = 5.94%, IDLE SPEED HC = 960, HIGH SPEED HC = 282. This is above the limits. Car appears to be running great and all the lines appear to be connected. Automatic choke works fine when cold then kicks down to idle without any problem. Could the EGR Valve or Catalytic Converter have a problem?

You likely just have a blown fuse at the diagnostic connector, check to see that you have 12 volts at pin 16 on the connector. See diagram of pin below.

My 97 Sonoma will not pass smog

You & we need to know what it failed for

What Emission Gas & what are your State limits
& what did your vehicle read?

You can study exhaust gases on the internet & see
what area of the vehicle needs work based on the gas

Have to educate yourself

Do not wait for someone to tell you things

You won't learn or remember if you don't
study on your own or don't start a binder &
take notes & copy web site info,punch the holes
& put in the binder

Then you take your info out to the car & make the
tests & fix things

Check engine light

The check engine light is because all check engine light codes are caused by components that affect emissions. It's not actually an engine problem, it's a problem with either your O2 sensor, MAF sensor, fuel/air ratio, pyrometer, or exhaust.

car diagnostic scanner

Check engine comes on and the car will not move in Drive! The car stays on but will have no power in Drive, if you put it in L gear it will move but at 5 miles an hour. Took it in to the shop and they...

When the service engine soon light (Also called the check engine light) is turned on this is to alert you to the fact that powertrain control module (computer) has detected a failure somewhere in the systems it controls, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.

Hi, At cold start my Accent 2008 is knocking since apprx. a month, i went2 times and dind t hear it ! at the third times the light '' check engine'' went on . teh code of knock sensor

If you detected the engine knocking and the knock sensor also detected it to the extent it caused the ECM to set a diagnostic trouble code (DTC) then simply replacing the knock sensor was a waste of time and money, a case of shooting the messenger because you don't like the message. If the car is under warranty or guarantee then take it to the dealer for complete diagnostics. Do not under any circumstances be put off by lame explanations that they can't do anything. Take the car to other dealers to get written reports on the car. It is very important to get the reports in writing as this gives you legal protection with regard to the guarantee.

Did not pass state inspection (vehicle)

First the fault codes,
U110C is No Fuel Level Bus Message
U0155 is No Cluster Bus Message.
Unfortunatly you have to be able to communicate with the instrument cluster with your scanner to diagnoise and I do not think an aftermarket scanner can do this.
