The pins seem correct for SAE J1850 VPW Protocol
Pin 2 Data
Pin 4/5 Ground
Pin 16 +12VDC

The data pin has a fuse (ODB 7.5A), check fuse. Location in engine compartment fuse box.

 

I had see something about OBD 7.5A fuse, I will relook it again.

For now my Camry is rebuilding his engine, so far it be ready, I take some pics and post here again.

[QUOTE=toyomoho;11233]Think Toyota started using ODBII on the 1995 Camry with V6 option. For sure all cars had ODBII by 1996. A car with ODBII would have a sticker on the hood stating this.

This car has ODBI (or whatever Toyota calls it). One does not need a seperate code reader for this car as it has an indictor output system using blinking lights. The number of codes is very small compared to ODBII. The dealer has a plugin reader for this system but have never seen any aftermarket types for sale.[/QUOTE

I actually own a 1994 Toyota Camry sedan it has both OBD 1 and 2 the OBD1 port is underneath the hood the OBD2 port is on the driver side behind a little cubby spot it's where your fuses are
