Shabazmo Posted July 7, 2008 Report Posted July 7, 2008 My brothers 4 speed automatic gearbox on his 2001 model 2.3 Galaxy has gone into limp mode, being held in 3rd gear all the time. The engine warning light is continuously on. Vagcom fault code is "0297 gearbox speed sensor G38 no signal intermitant". I have clreared the fault code to rectify the problem but it returned 10 minutes later. I have changed the G38 sensor which incidently is the Ford name for the gearbox turbine shaft sensor, cleared te fault but the fault returned after a 10 minute drive. Any ideas? Thanks Quote
MrT Posted July 8, 2008 Report Posted July 8, 2008 I had a very similar issue around two years ago when I bought a new aftermarket MAF sensor. My engine warning light would come on, the ESP (or similar light) and the auto gearbox lock into gear. I had errors showing on VAG COM (words might not be exactly right) - MAF sensor Implausible reading, Engine Torque out of specification, Gearbox Speed Sensor and a few others. These were all caused by a dodgy MAF sensor, I could not see how they were related or affected by the MAF sensor but it must have somehow been screwing the engine management system up. Put the original back on, cleared the faults and all was OK. So it could be a totally non related sensor or just a wiring fault. Quote
Shabazmo Posted July 11, 2008 Author Report Posted July 11, 2008 Fault is now permanent. took it to the Ford dealer who found that the feed voltaage to the sensor is only 2.5v instead if 5v so the fault is presumed to be the TCM transmission control module. Hpefully this will fix it. Quote
Shabazmo Posted July 15, 2008 Author Report Posted July 15, 2008 Problem now solved but what a palava. New TCM orderred and fitted by Ford. This time lots of fault codes and problem not fixed. Part mumbers were the same except the last letter. Ford insists it is the correct part. Dealer notes that there is one wire short and speaks to ford and VW as its a VW part. VW says that since its mated to a 2.3 Ford engine then they do not support it. Ford eventuall order a different TCM part from Germany and problem solved. Quote
Keanu Posted April 14, 2010 Report Posted April 14, 2010 model 2.3 Galaxy has gone into limp mode, being held in 3rd gear all the time. The engine warning light is continuously on. Hi, I have the exact same problem but with different fault code OXO10E What was the overall cost for fixing the TCM? Quote
