Question about Volkswagen Jetta

1 Answer

I have a 2003 Jetta 2.0 automatic. When the car is warm I'm having some shifting issues but the real problem is when I get up to a speed of about 65 or 70 and i take my foot off the gas, the tach drops to about 1000 rpm and then shoots back up and gets the transmission stuck in a gear and the only way to reset the problem is by turning off the car. The dealership has already replaced the control module with no difference and now wants to change the transmission. Any ideas on what the problem could be??

Hello! Which control module did the dealer ship replace; The transmission control module? If so, ask if they changed the Transmission Vehicle Speed Sensor...This particular sensor is suspect...There isn't any way to test it and it's location is on top of the trans axle and very difficult to access...

Let me know what was changed...Guru.....saailer

    Hello! There is another sensor that needs to be eliminated as a probable cause...Actually it's two sensors in one...There isn't a cable between accelerator pedal and throttle...The position of the pedal (drivers intention) is communicated to the Electronic Control Module (ECM) via the Accelerator Pedal Positioning sensor...And the Throttle Positioning Sensor...Two sensors in one...They can be tested with a volt meter set to read 5 volts...The sensor is connected to the pedal...A new sensor can be purchased for $190...We can test them with a volt meter set on the 5 volt scale...Components are tested with connectors in place...A wee bit difficult to get to but with a bright light and a mirror it can be done...You'll need two safety pins...Wire colors are...White/Blue and Yellow/Green for one sensor and Brown/Blue...Gray/White for the other (Push one pin into the rear of the connector on the rear of the gas pedal on White/blue and the other on Yellow/Green...Connect the + probe to White/Blue and the - probe to Yellow/Green...Start the engine...Leave In park...Meter should read less than 1 volt (.85)...Slowly depress the pedal....Voltage must rise smoothly to 4 volts (open throttle) without skipping, jerking or jumping...Repeat the exact same test using the Brown/Blue (+) and the Gray/White (-)...Readings must be the same...It is important that voltage rises smoothly...If any of these readings are not as described the sensor/sensors are defective...Send a comment with results...

    Yes the dealership changed the transmission control module. And they never mentioned anything about the transmission vehicle speed sensor. Is this part of the transmission also??
    I am taking my car to another mechanic since the dealership won't work on the transmission, they will only replace it, so i will be sure to mention the other sensor to the new place. Thanks for your input!!

    Hello! The Transmission Vehicle speed sensor is not part of the module but an external sensor to the transmission...It is a very costly item to replace due to its location...The Accelerator Positioning Sensor would be the first part to test...When you reach a speed of 65-70 MPH, and take your foot off the pedal the problem occurs...There are two sensors working together to maintain speed rather than dropping to idle when you remove your foot (which is what the engine is doing)...The other sensor is the Throttle Positioning sensor (TPS)...Both sensors are encapsulated together and connected to the gas pedal...That's the part that cost $190...

    Having a wee bit of knowledge will keep you from being taken for a ride...
