1997 subaru impreza outback speed sensor: Where is it located?

It probably needs to be adjusted or you got a bad one it happens

Well forester , outback and impreza share the same engine , transmission and maybe a couple more parts unless its an sti

There are actually two Vehicle Speed Sensors (VSS). I'm going to assume you have a 2.5 liter engine and an automatic transmission.

The Vehicle Speed Sensor 1 (output shaft rotation sensor) is mounted to the extension case (from the outside of the case). The sensor outputs a pulse signal which is transmitted to the TCM where it is converted to vehicle speed.

The transfer clutch drum is connected directly to the rear wheel driving propeller shaft. Vehicle speed sensor 1 on the AWD model detects rear-wheel speed.

Vehicle Speed Sensor 2 provides vehicle road speed information to the ECM. The ECM uses this data to properly determine ignition and fuel delivery curves. The sensor consists of a reed switch and magnetic rotor turned by the speedometer cable.

One rotation of the magnetic rotor opens and closes the reed switch four times, producing a digital signal which is converted to vehicle speed by the ECM. The sensor operates whenever the vehicle is moving with ignition ON. As the transmission rotates, the speed sensor sends a pulsed on/off signal to the ECM.

The speedometer uses VSS 2 for it's signal.

Hope this helps (remember to rate this answer).

Could be a loose connection, a bad ECM or maybe you need to have your ECM re-flashed by the dealer?

I assume you're referring to the Speed Sensor, and the 2 wires coming from the Speed Sensor? Is your speedometer totally inop, or is it giving improper, or sporadic indications? I'm not familiar with Subaru, but wiring for speed sensors are generally the same for most 96 and newer vehicles. That 2-wire harness typically runs to a disconnect... to the PCM... maybe another disconnect... speedometer. If you have access to schematics, or wiring diagrams, you would need to obtain a few plug and pin numbers, locate the components, then trace a few wires. I'd suggest first running a diagnostic in order to obtain any possible fault codes, and use that as a good starting point.

location of knock sensor on 1997 impreza

on the top of the engine block under the inlet mannifold

there is a little black or white depending on the brand rubber buttong located on the clutch pedal that just pops out and pops back in. what happens is the pressure ends up putting a dent in the rubber and so it no longer makes proper contact. its is like a 2 dollar part. good luck

P1540 VSS(vehicle speed sensor) signal to high, P0500 vehicle speed sensor malfunction.

Drive it till there's not a drop of gas left in it for ease of removal.
