Question about 1999 Ford Escort
I've got a 99 ZX2. The VSS wires are blue and white with black trace.I've replaced the VSS (new, then put old back in), Instrument cluster (used, but person said it worked and came out of his car to put in a S/R cluster).Went to a junkyard this week and tried another instrument cluster, no change.
Testing i've done:Checked continuity of wires from VSS to dash, checked ok.Blue wire and white wire with black trace (black harness to instrument cluster), both read 8.5 volts while grounded to chassis. Traced wired to fuse box under hood. Is the 8.5 v reading correct? 240 ohms @ VSS. 230 ohms @ dash (from what i've found, within proper range). Hooked up multimeter/Ohm meter to the VSS wires at the cluster and drove it. It starts beeping faster (continuity) as you go faster. Checked with key on and off.I've read there will be shifting issues if the PCM isnt' getting the correct signal. No shifting issues after about 2 months.I'm not sure what's going on. Either the instrument cluster (doubtful since i've tries two) is bad or possibly the PCM (or EEC as mentioned in the post above)? Is there a component i'm not taking into consideration?Thanks.
I'm sorry, I have to ask, this is an automatic right? That out of the way, Does the trans shift different when you drove it with the Vss unplugged when you had the ohm meter on it? 8.5 volts? Something sounds wrong here. I'll have to look up the wiring diagram before I can say thats a bad reading but it should be battery voltage (14 volts running) or 5 volts?
