Hello all,

This is my 1995 Toyota Corolla, and the engine light turns on and sometimes off. The mechanic diagnosed and found out the ECU code is 71. This is the same code after fixing for a couple of times.

Anyone know what this code means, and most importantly whey the engine light turns on/off now and then. Thanks for all your help.

Code 71 is a fault with the EGR System.
