col_panic Posted February 3, 2004 Posted February 3, 2004 I just ordered an Equus OBD I code reader and then realized the application sheet only shows it for models through 1993. The emmisions sticker does not say OBD II compliant. I found a site that says in 1994 Lexus began using OBD II, but they were not fully compliant. Is there a specific reader for the 94 and 95? Will an OBD II work, but not fully?
col_panic Posted February 9, 2004 Author Posted February 9, 2004 update: i called equus the same night and they cancelled my obd i scanner order. found the obd ii scanner from midway auto supply for $119 and free shipping. got it today and it works great. the check engine light went out yesterday, but the reader shows the only stored code as P0135 - 02 sensor heater circuit malfunction (bank 1 sensor 1). i hardly ever need the heater in south florida so i am happy this was the only code. i love this reader. thanks again for the help.
SKperformance Posted February 9, 2004 Posted February 9, 2004 It is saying the oxygen sensor is defective for the engine,not the hvac system. So you are running rich right now and wasting gas until you fix it.
col_panic Posted February 13, 2004 Author Posted February 13, 2004 doh! is that user serviceable? i know my way around older engines well, but haven't done work on post 80's cars much.
SKperformance Posted February 13, 2004 Posted February 13, 2004 it is only a big bolt essentially in the exhaust manifold .
col_panic Posted February 14, 2004 Author Posted February 14, 2004 excellent. that $50 from lfs is going to come in handy :)
jbrubaker Posted February 16, 2004 Posted February 16, 2004 I have a 1994 Lexus ES300 If it has this engine in it will this Reader work for mine as well? Where is the interface located? And where is the engine model located?
jbrubaker Posted February 16, 2004 Posted February 16, 2004 Found that I have the 1mz-fe Engine, where is the interface for reading the plugging in the code reader? And is there some that work with laptop & Software you would recommend?
blake918 Posted February 16, 2004 Posted February 16, 2004 Pull the fuse panel cover inside the car below the mirror controls, and you will see the plug(it looks like something you'd see on a computer) next to the fuses. If you can't find it, I'll snap a pic for you.
SKperformance Posted February 16, 2004 Posted February 16, 2004 It is to the right of the fuses behind the fuse cover which is to the left of the steering wheel. you are right it is a 1mz-fe engine and obd2 there is also another data connection on the top of the intake maniold of the engine on the right side
jbrubaker Posted February 16, 2004 Posted February 16, 2004 Thanks, guys, I will be checking it out tomorrow.
