Speedo is going nuts... (Check Engine Light!), (Updated!) Options

[[Freemantle]]

Topic sums it up pretty well. My speedo jumps sporadically and eventually dies at zero, bouncing up sporadically. Whenever I had problems with this before it was always electricity problems screwing up the voltage readings from the Hall effect sensors. No dice, I tested it thourougly; my electrical system is running strong.

My next stop is the vehicle speed sensor. On my CRX it's right over the transmission housing, but I can't seem to find it on this 7A-FE. Is Toyota hiding it or am I just looking right past it?


Edit I threw a solid CEL today! I the car was slow to start, and then after about 10 minutes of driving i threw a solid CEL (but no limp mode). Where do I jump to pull the CEL and is there a directory of CEL definitions anywhere around?

it would help to know what year your car is. fill in all your profile info.

if its obd1 you can just jump TE and E1 with a wire. then count the blinks to read the codes. if its obd2 then u need a code reader.

if your code comes up as speed sensor. then it might be your speedo sensor on the tranny OR your gauge cluster. look around on the tranny to find the sensor. on my GT its right on top .
