ok i have a full system to go on but ran in to a problem once got it on the ramp and see the sensors and on the manifold and decat they are both screw in types with block of screws and the standards are flange type . and not sure how many wires they have.
i was trying to find out what universal ones i needed as see some were that toyota had special ones . i found the original denso ones but unsure what models are the right ones and i know you cant run the upper and lower on each but all is just what i have been reading . im basically looking for options in getting the right sensors or other simple ways of making it work with out codes and running bad . the car is a 94 SS2 PS i will have to extend the wires so will be cutting them any way how have you all solved this problem

35 bucks, and just used a threaded type o2 sensor, 4 pin. 1 off a lexus. it works fine! |

how many wires per sensor do u have on those 2? 2 pin wires or 4 pin wires?
and im not too sure about the temp sensor for the cat, i know the 02 is more important. |

My ST202 96' has a 4 wire -you should be able to see the o2 sensor loom by the extractors. I can't say if earlier years have less, but I'm pretty sure they're 4 wires also
Can't remember the cat temp sensor wire count maybe 1,2? On the dash you have the box with some wavy lines above it thats that sensor. Replace the sensor or clear the code. We found out years ago with a S14a that it went into safe mode -------------------- |
