OBD II connector troubleshooting 101

I had the same problem with my 2000 Elantra. the OBD II connector pins get squished and won't make cantact with the scan tool, therefore no connection. the solution is to bend the pins back so they will connect to the scan tool.


FIRST! check your lighter and radio fuses (which you have already done). If possible, make sure your scan tool is working properly, try it on another car. If it is functioning properly, remove the 2 screws holding the obd II connector to the dash. Look for obvious signs of corrosion, damage, or stuff that shouln't be in the connector (rocks, gum, etc.) clean the connector with a good electronics cleaner (I use the CRC stuff), you can usually find it at you local parts store, radio shack, or even wal mart. hose down the inside of the connector thouroughly and allow time to dry.

check for voltage between 4 (gnd) & 16 (+vcc) then 5(gnd) and 16(+vcc) with the ignition on the voltage should be between 12v-16v (these pins may be different on other cars, look for an OBD II connector pinout diagram if your car is different). If this voltage is not present at either pin, the problem is not the connector. check your fuses and wiring. if this voltage is present at both pins continue.

Here's what I did. with the connector free from the dash, you can see the back of the connector where the wires enter the connector. on either side of the connector there may be a white clip. pop both of them off. you should be able to push a small screwdriver or pick in that space to pull the pins back out towards the outside of the connector. do one at a time so you can tell if the pin has moved back out into position. do this for all of the pins. Try to connect. if still no luck try again to push out the pins and reconnect.

If your connection is restored, replace the clips, screw it back into the dash. Return your car to the lousy DMV where they will proceed to tell you something else is wrong which they neglected to tell you on your first 10 visits!! :-)

Stuff thats good to know:
some auto parts stores will connect their OBD II scan tool to you car for free. auto zone is one place
some times the computer will need to reset to restore a connection to the scan tool. to do this simply cycle the ignition off (wait a few seconds) then on again.
online auction places are a excellent resource for USB to OBD II connectors to connect your laptop to your car. there is lots of OBD II diagnostic freeware out there to go with your newly purchased connector.

Good Luck

SOURCE: P0320 & P1391 OBD codes displayed.

P 0320 = No Crank Reference Signal to PCM. No Crank (shaft position) reference signal detected during engine cranking (starting).
P 1391 =Intermittent Loss of either Camshaft Position Sensor or Crankshaft Position Sensor.
Hav you attemtped the "3-Key-Ons" method to see these codes on your digital Odometer (assuming you have one) Turn the Key from Off to On (not start) three (3) times. On the third (3rd) time leave the Key in the "On" position (not start). Look at your Dogotal Odometer (if so equipped). The Codes, one at a time should appear. The Last Code will be "P donE".
If te engine is performing without problems: disconnect the negative side of the Battery and wait at least 5 to 30 minutes. Reconnect the Battery. Re-preform the 3-Key-On's and see if and Codes are now showing.
If you start having Start or Running problems becoming more and more frequent: consider replacing the Crankshaft Position Sensor. If this sensor "fails" you may not get any fire to anything, as this is the signal that is necessary for the PCM to initiate the Firing Sequence. The PCM will not send a signal to even the Ignition Coil to begin.

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.

Retrieved codes P0191, P0152, P1246, P1233 and P1000 on my 02' Taurus 3.0 OHV. What would be the most likely culprit causing these codes?


P1000 - Monitor Testing Not Complete The on board diagnostic II (OBD II) monitors are performed during the OBD II Drive Cycle. The DTC will be stored in continuous memory if any of the OBD II monitors do not complete.
  • Vehicle is new from the factory
  • Battery or PCM had recently been disconnected
  • An OBD II monitor failure had occurred before completion of an OBD II drive cycle
  • PCM DTCs have recently been cleared with a scan tool
  • PTO circuit is shorted to VPWR or B+ or PTO is on during testing
The DTC does not need to be cleared from the PCM except to pass an inspection/maintenance test

Trouble code po420?


that is the code for the catalytic convertor. it is either bad or not working at optimal levels. In most cases this in not such a big deal unless you live in a state that does emission testing buy pug in and not tail pipe emissions. Most states now use a quick OBD II plug-in test to check emissions compliance on 1996 and newer vehicles. The plug-in test is faster, easier and cheaper to do than a loaded mode tailpipe emissions test on a road simulator or dynamo-meter. The rules in most states say to pass the OBD II plug-in test, the vehicle (1) must have a fully-functional OBD II system (Check Engine lamp works and the diagnostic connector communicated with the engine computer), that the Check Engine light must be off and that there are no current codes in the computer's memory. If this is the case than you're going to have to replace the converter.

The check engine is on. would like to know where to start checking


We will can really offer any help other than to have codes scanned and see what code or codes is stored in the computer there is just to many things that can cause a check engine light to be set.

"The 'check engine' light is reserved only for powertrain problems that could have an impact on the emissions systems," says John Van Gilder, General Motors' lead OBD development engineer.

Exactly what the OBD system looks for depends on the make, model and year. The original systems varied widely in their capabilities. Some did little more than check whether the various electronic sensors and actuators were hooked up and working.

That changed by 1996, when, under OBD II regulations, carmakers were required to install a much more sophisticated system that essentially acts like a built-in state emissions testing station. The computer monitors and adjusts dozens of components and processes. For example, it continually samples exhaust emissions as they come out of the engine and again when they leave the catalytic converter, a device that removes carbon monoxide and hydrocarbon pollutants from the exhaust. The system also monitors your car's fuel system to ensure that gasoline vapors are not escaping into the atmosphere through a leak or even a loose or missing gas cap. In most cases, if a problem occurs, the computer will wait to see if it corrects itself before turning on the light. Modern OBD II systems are so thorough that state testing centers increasingly are checking for any stored trouble codes and foregoing the traditional tailpipe emissions test.

Keep in touch.

Emission test


Why aren't they just using the OBD II port instead of the dynomometer? Which state are you in? In Washington, where I work as an emission test specialist, we don't even use the dyne (rollers) to do the test. The OBD II port doesn't require the car to be taken out of park.
If you have to resort to it, just pull the TCS fuse for the test. The TCS won't activate and you won't get any emissions error codes.
Be sure to check with the testing facility before you do this. They may not allow it if it may be considered a safety issue.
I wish you the best!

Emissions test


Most of the Smog testers need to use the speedometer for testing since they have to test your vehicle emissions at 15mpg, 25 mph, etc. So you will likely need to get that fixed before your testing
