SES...OBD1...can't pull codes

My 96 Taco has the OBD1 port. This past week the SES light has been coming on. I can clear it, but it comes back on within a couple of days. According to my Haynes manual to pull the codes I have to turn the key on, engine not running, and jumper out the TE1 and E1 terminals in the OBD1 port. I have done that, but the SES light is not blinking the code. It stays lit solid, no blinking at all. I have also tried jumpering out the terminals before turning the key on with the same results. Has anyone run into this? Any suggestions?
When the light comes on I have noticed no difference in the way it runs or idles.

 

You should go to autozone or equivalent and have them scan the codes. Doing the wire jumper trick is a major pain in the ass.

 

Thinking you are probably right. I have used the jumper on other vehicles in the past without issues. This is the second time I have tried to pull the codes on this truck and was unable to. The first time was about a month ago. I cleared the code then and the light stayed off until a couple days ago.

 

I put my money on a O2 sensor code.

 

Being that it is a 96 check for the obd2 port under the dash . It should be tucked in the corner on the drivers side where the dash meets the center console area . you can use any scanner your local zone or a dance auto has to check or clear it


Wait just reread . You are saying the ses light. This is the light for your airbags, you might be better off having a shop scan it for a short.

 

SES... service engine soon. Also known as the check engine light.
The OBD1 port is under tho hood attached to the driver's side of the intake manifold.

 

Thanks. You are correct. There is an OBD2 port under the dash. I saw the OBD1 port under the hood and figured that was the only port. Wonder why it has both? Maybe Toyota was using up old engine harnesses???
Anyway, I have an OBD2 scanner, so I will check it when the light comes back on. I have a feeling that it is an evap code. The fuel pump cover leaks. I would think this would constantly throw a code, but it doesn't. I will replace the tank when I do the frame swap.

 

Obd2 was required per US regulations starting in 95. Most vehicles in this time era still have various hookups as the obd2 was added to existing harness designs versus doing all new

 

Yeah. I knew about the OBD2 requirement. Just wasn't sure about the year.

 

I think that port under the hood is a diagnostic port for dealership mechanics to plug their super-duper 'scanners' into.

 

Could be. It is definitely an OBD1 port, tho. I wouldn't think the dealer would use it instead of the OBD2, but what do I know.
