I just recently bought the car listed above used 2.5S, 6 speed manual. The speedometer stays at 0. I changed the speed sensor and I have done more research on the subject and I can't find out what may be causing this.

Hi,

If the sensor is new and there is still no reading, we need to scan the can bus system to determine where there is a break down. CAN stands for controller area network. Basically, the vehicles modules, computers and so on are tied together via a few wires.

Here is a quick video showing how it's done:

Now, (and this is a guess at this point) I suspect it is related to the meter system. However, I need a code to make the determination. Otherwise, we need to start checking things.

Here are the diagnostics for the meter system diagnostics. See if it is something you can do. However, don't replace things until we know the most likely cause.

Note that the flow chart identifies a specific code.

Diagnosis Procedure
Symptom: Displays "VEHICLE SPEED CIRC [B2205]" as a self-diagnosis result of combination meter.
1.CHECK COMBINATION METER INPUT SIGNAL
1. Start engine and select "METER/M&A" on CONSULT-III.
2. Using "SPEED METER" on "DATA MONITOR", compare the value of DATA MONITOR with the speedometer pointer of the combination meter. Speedometer and DATA MONITOR indications should be close.

Is the inspection result normal?
YES >> Perform ABS actuator and electric unit (control unit) self-diagnosis. Refer to CONSULT-III Function (ABS)" See: Antilock Brakes / Traction Control Systems > Scan Tool Testing and Procedures > ABS See: Antilock Brakes / Traction Control Systems > Scan Tool Testing and Procedures > CONSULT-III Function (ABS) (with VDC/TCS/ABS) See: Antilock Brakes / Traction Control Systems > Scan Tool Testing and Procedures > VDC/TCS/ABS.
NO >> Replace combination meter. Refer to See: Instrument Cluster / Carrier > Removal and Replacement.

Let me know what you find or if you have other questions.

Take care,
Joe
