Check engine light will illuminate and codes should be read with an OBD1 tool.
i do believe obd1. the engine is a 1uz-fe
94 buick lesabre was right at the change over( obd1 to obd2) some have an obd2 connection with an obd1 computer. this can only be read by buick garages. go to auto zone or checker auto and they can tell you.
No difference in the engines, just in the ECU (Engine Control Unit) programming. OBD2 doesn't let you have the diagnostic codes without a code reader.
The '95 Contour has OBD1. You would need a reader for that older system to read the codes properly, and readers for OBD1 tend to be somewhat expensive. The best thing to do is take it to a shop that has the equipment.
Depending on the year, use either an OBD1 or OBD2 code scanner. You can borrow, rent or buy a code scanner from most auto parts retailers.
No , all engine's before 1995 where obd1 after 1995 obd2. Same goes for the b16a2 , if you have for instance a engine from a '94 Del Sol vti (b16a2) It is obd1. Lex
Well you can go down to advanced or auto zone the will ron a digonistic (OBD1)on it if its 96 or newer if its older you can take it to your avrage mechenic and they can run the obd1 test on it and it will give you a general idea of what it could be and reset all the codes
there are many codes to refer to. Pick up a Haynes repair manual and they are all listed inside.
There is no OBD connection on a 1990 Nissan as that is an OBD1 vehicle not OBD2. However there is a way to read the codes. https://codes.rennacs.com/Petrol-Engine/Japanese-Korean/Nissan-Engines.php
yes you can read the codes however not in the form of obd2. check engine or shut down light will come on. there is a obd1 plug under the dash put a paperclip in the first two holes (first hole on top and first hole on bottom). by doing this it will make the code flash through the check engine or shut down light flashing a number of times . these numbers are the fault code. count the numbers and look up the code to see what the car is telling you.
If you aren't a master mechanic, take into the dealer and get them to do it. They will just hook it up to a computer and disable them digitally. If you are a mechanic, use the obd1 to disable the auto power locks. alternatively you could disable the power supply to the auto locks making them manual lock.
