Replacing the TSS and OSS sensors

[tgirard]

I have a 2008 Edge SEL with 55,000 miles. Noticed recently that there was a slippage between the 2nd and 3rd gear while accelerating. It wasn't bad, just that the RPMs would rev a bit higher than into 3rd it would go. It also stalled going up a hill one day from a dead stop and the "wrench" signal came on. Restarted the vehicle and it was fine. So, i brought it into the shop and they ran diagnostics and it came up with having to replace the TSS and OSS sensors. Has anyone ran into this problem and was it taken care of by replacing those sensors? Thanks, Tim

Do not ignore this problem!!! Read some other online forums. I have an 08 MKX and the same is happening to me (significant amount of others as well from what I read online) and I took it to the dealer as well. Of course they did not experience the problem. So they said nothing was wrong twice. With mine...when I am either stopped or in stop and go traffic...I hear a thump and when I try to accelerate the RPM's go really high but the car will not go more than 10mph as if I am in neutral. So what I do is put the car in park, turn off ignition then restart and its fine. The dealer told me the 'CAM PHASERS' are bad and its going to cost about $2300+ to repair the problem. From reading the other online forums, this problem is common and there is even a watch thread on it. DO NOT IGNORE THIS PROBLEM! Most of the other 08 Edge and MKX owners have experienced the same problem. The lucky ones were in warranty and got it repaired for free. Your warranty is expiring soon...be sure to take to dealer for ANY similar issues ASAP and keep a paper trail! This job is very expensive because they have to take the engine down to get to the cam phasers and from what I read online takes a minimum of 10hrs labor. Parts cost a lot as well. Most people ended up having their car in the shop for 1 to 2 weeks to get this job done.
