engine lite came back on

01 std cab 2.7 4x4 5 spd 70.000 + engine light keeps coming on every few weeks than shuts off , it happen a few time tested it and gave me a couple differnt codes o2 sensore map sensor and it just came on today. Any thoughts would be excellent

 

my guess is the o2 semnsor

 

what codes were they?

 

there is a manual for your taco in which you can purchase that has error codes and how to troubleshoot them it also comes in a cd. last i checked it was availbale in ebay for $5.00 hope this helps i have one for my 2nd gen taco.

 

well, you can look up the codes, or you can post them here and im sure somebody has probably dealt with them before
