Hey All,
I purchased this TL from Auction and discovered it has been tinkered with quite a lot. I am getting the following trouble codes and there is a lot of electrical wire splicing that has been done. If I reset the codes the car will operate OK and rev over 3500 RPM but after a couple higher RPM gear changes the car will no longer rev over 3500 RPM.

P0135 and P0155 for o2 sensors - These codes show up immediately after clearing codes.
P0498 - Evap Emissions System Vent Valve control circuit low
P2648 - A Rocker Arm Actuator Control Circuit Low Bank 1
P2552 - Throttle/Fuel Inhibit Circuit

I replaced the VVT solenoid and oil pressure switch and the Intake Manifold Runner control actuator to clear some of the other codes I was getting.
I took it to my local trusted shop for a deeper diagnostic and they suggested that due to the amount of tinkering with the fuse box and wire splicing that I should start by replacing the ECM/PCM, Fuse Box under the hood, and the Engine wiring harness. I was thinking of starting with the ECM but am worried that the existing electrical state may fry any replacement ECM.

I am in the Dallas area and looking for an 05 TL M/T that I can get these parts as a set.

Any other guidance would be greatly appreciated as well.

The only car-part.com 2005 six speed I could find near you is in New Mexico. They have the ECM, engine fuse box and engine wiring harness listed.

If possible, you best 'jump' on it before the frankenstein peeps snatch up these parts.

Good Luck!

 

there's a few grounds that could be loose, there is one by the throttle body that causes rocker arm A error if I remember correctly.

 

Looking for parts and will check the grounds.

Thanks!
