Yes, you ar still out of limit, probably an open circuit.
Key on, with the engine off, you should have 5V on the engine side between 2 and 3 (power supply). Once you have verified you are getting power as needed the rest is all about verifying signal, and part integrity.
Oh and make sure the signal wire is ok, this normally is not the case, but on a 20~ year old vehicle anything is possible.
Here is a GREAT article explaining the sensor and how it works, I would skip to the 3 wire sensor part.
