so i have a 92 4runner, sr5 speed, 4x4 etc. its got over 280k on it and recently its been a pain in the butt. its flashed 4 codes- 14,42,43,71. i know what they all mean. im curious where the VSS sensor is on it (code 42), cause i keep reading that it might have two? i know there is a ABS speed sonsor on the rear diff and i was wondering if that is related to my problem, cause i recently replaces the seal on the rear diff. i was also curious what would cause a code 43 and what i would check or replace to fix it. as far as the EGR, i replaced the valve and i think i didnt clear the old codes out when i did. any help would be greatly appreciated!
