TPS and speedometer wire locations
1 Attachment(s)
I know tps and speedo wire locations have been asked for before, I found them so thought I'd make a post.
I located a tps wire that gives absolute throttle position measured at the throttle plate. It is located at the factory ecu in the first plug location 1J. It provides 0.4-0.8v with 0% throttle, 3.8-4v at 100% throttle, and with all the values inbetween. The attached pic shows the tps wire location in the harness. The speedometer wire is a green w/ red located in the radio harness |

The speedo has to come off of the transmission control box(or something like that) I have yet to find that box. It does not come out of the factory ECU. Not that I could figure out.

Im sure I have read somewhere in here, the speedo wire is connected to the ABS, though I could be mistaken .

Thats why if ABS goes bad, u will not get the speed at all and when u have Mazda's IDS, you can use it's monitor pid to read each sensor's speed. |
