tricking the computer
Let me ask all you Dodge gurus
back in the day if a sensor went bad all we did was put a resister of the ohms needed was put in the female part of the wire,and it fooled the computer to thinking the sensor was ok i did this to 100s of vechicls that the costumor could not aford the part. all sensors do is send a electrical signal to the computer. so why cant we do that to these sensors on modern trucks? there is videos on yt about how to test a sendor so if we can test it why cant we fool the computer? by putting the correct ohms resistor in the connecter.its all electric right.

Some sensors return an analog signal varying form 0 to 5 v. A resistor would give a fixed voltage...therefore the computer would make other things work/not work based on that signal. Not a good way to do it at all. Sensors on these rigs are cheaper than my other vehicles. Seems like bad medicine to me.

Dealership DA`s
Well after trying all the online tips to do a self OBD with the key, even the old chicken foot hanging from the turn sig arm,I decided to call a couple dealerships. and both never heard of a 1999 that has built in OBD. well isnt that special.but there happy to have me spend 100 bucks to have it towed in and 98 bucks just to hook it up to there code reader, hell yea 200 bucks and not even fixed yet. gota love it.

The dealers you called are morons, but yes some EARLY 99's will also not work using the key trick. You simply need a code reader.

Hold the odometer reset button with the key in the off position.
Turn the key forward to the position directly before the position in which you would turn over the motor.
Immediately turn the key back to the off position.
Turn it to the on position again, then to the off position,
turn it to the on position again, then to the off position,
and finally turn the key to that same on position for the last time.
Now release the odometer reset button after you left the ignition switch in the on position and the magical OBD2 code display will occur.
The trick for my 1999 Ram is to hold the Odometer Reset button while turning the key to the on and off positions three times, then on the fourth turn to the on position you leave the switch on and finally release the odometer reset button.
This sequence causes the truck to run a diagnostic check on the electrical systems and will help you identify what is going on. How to understand the codes, however, is something I am not aware of.
O'reilley Auto parts rents code readers to the general public. If there is an O'reilley in the area, that's where I would go before handing $200 to the dealer. Either that, or find a local high school or college with an automotive department and try and get close to one of the teachers for some help. Sometimes they allow for vehicles to be donated temporarily for work to be performed.
Best of luck...
