Hi All,
I've searched all over to find out where the 02 sensors were located on my 93 TLC and finally found them. I wanted to quickly add it here, just in case someone else had a hard time finding them. They're side by side just before the cat and I'll be replacing them with these Bosch 02 Sensor replacements, as well as with this EGR valve, all from Rock Auto. Replacing them due to getting 'Check Engine' light and codes 28 - for 02 Sensor and 71 - for EGR system.
BOSCH 13448 Bosch Validated Oxygen Sensor
Upstream Right
BOSCH 13081 Bosch Validated Oxygen Sensor
Upstream Left
WVE 4F1673 {#226508, 2562066010, EGR4002} Includes Gasket
1. Does anyone know which one is Upstream Right and Upstream Left? Is it right or left standing in front or back of the TLC?
2. Does anyone have any opinions about the parts I've ordered?
I'm fairly new to working on my 93 TLC but experienced enough in working on cars, but hardly any tools to do major things.
The attached Exhaust Map helped me to find out where the 02 sensors were, now I just need to know which is upstream right and left.
Thanks in advance!
