1991 Cressida Grande speedo intermittent probem
Hi All. I've been experiencing my 1991 Cressida Grande's speedo has been intermittently not working for a year or so now, to the point where it now doesn't work more often than it does. I replaced the ATM speed sensor with no appreciable effect. I cannot carry out the tests shown in the Toyota repair manual because there are 3 wires connected to my speed sensor (R-L, B-R, and Y-R), whereas the manual shows 2 wires connect to the sensor (BR, and G-W).
I now suspect the problem is faulty wiring which I am investigating.
If someone has experienced this problem I'd appreciate your comments.
