My OBD2 is not picking up my speed sensor but my speedometer is working fine does anybody have a suggestion where I can start looking?
​​​​​​ my car is very heavy on juice and everything else is perfect my short-term fuel pressure long-term fuel pressure and my oxygen sensors are working perfect all I can think is that the speed sensor has got something to do with the fuel economy. My car speedometer is working perfect but the OBD2 says that the speed sensor is faulty,but my speedo is working. It suddely went geavy on fuel, , i now get 5km per liter,before it was almost 10 km per liter

 

By "My OBD" do you mean your code reader? What is not working? What symptom are you chasing?

 

My Chrysler Crossfire is super heavy on fuel all the sensors are working fine my oxygen sensors are working perfect and the long-term and short-term fuel trim is ok the only think the diagnostic centre cannot pick up is the speed sensor but my speedometer is working

 

Exactly what instrument ("Diagnostic centre") are you using?

If the car is running well, what are you trying to determine or correct?

 

Ok, discussing this with others - the diagnosis is to suggest you clean or replace the MAF sennsor.

I/we still don't understand your concern with the wheel speed sensor, that has nothing to do with fuel consumption.

 

My car suddenly gives me only 5 km per litre all the sensors are ok except for the vehicle speed sensor is not being detected by the OBD2 my speedometer is working

 

Hi there
What does it matter I'm using a OBD sensor that I plug into the plug where you got a plug-in diagnostic my car is very heavy on juice and everything else is perfect my short-term fuel pressure long-term fuel pressure and my oxygen sensors are working perfect all I can think is that the speed sensor has got something to do with the fuel economy. My car speedometer is working perfect but the OBD2 says that the speed sensor is faulty

 

See post #5, this thread is like a broken record.

 

is that so??
Then your like a broken toilet

 

Way to win friends and get help. I’m done.

 

Sad that escalated quickly.

 

No, you "feel" that the speed sensor has something to do with it.

It doesn't. The speed sensors drive the speedometer and ABS systems, if you have a manual transmission, that's all the sensors do.

 

So he does drive a 2003 Crossfire (2004 US) with manual transmission.

 

Yes. So no Transmission control module - the speed sensors can't have any effect on mileage.

 

EVERYTHING MATTERS. Keep in mind, we are not standing next to your car, all we have to go on here is the few words you type.

"Heavy on juice"? Just what is your fuel mileage? How bad is it? Crossfires are not known for good gas mileage.
