2002 Toyota 4Runner SR5 or Tacoma V6 Code P0770( shift solenoid "E" malfunction)

 This under the Toyota Powertrain warranty is in effect for 96 months or 80,000 miles. The ECM(PCM) needs to recablibrate.When you saw this code the first thing you should do is take it back to the dealer.   But if you out of warranty what you can do is remove the glove compartment door. when you see the ECM  is the second connector from Left to the Right hand side( E10) 22 wire color( wht/red) and 23 (yel/red) and check the ECM terminals SP2+ and SP2- measure the resistance. It should be 560 to 680 ohms, if resistance is as specified the ECM need to replace. Speed sensor from transmission it needs to be check out too.  Resistance should be 560 to 680 ohms. what I found is the resistance at termianls sp2+ and sp2- are 6790 ohms.

2001 Chevy Tahoe ABS Code C0265

Cause: A poor connection at the EBCM ground. The EBCM Ground is located on the frame beneath the driver's side door. The EBCM Ground can be identified as the heavy(12-gauge) wire.  Try to clean the ground and tighten with washer and nut to see if you can fix the problem.  Good luck.

Toyota Camry code P0401

On this car was the comment problem on EGR system. What you need to do is  to check your EGR first to see it work or not. second check the vacuum system. Third check the EGR vacuum modulator. Sometime the VSV is bad, I replace once.

2007 BMW 328i N52 Code 2A82 P0012

Only problem was when the car started the RPM is not satiable for 5 seconds after the car runs fine. Please don't replace anything before you check. On the 2006 down the dealer will recommend you change too many parts.  The  car was running fine no check engine light. It just the oil leak on the valve cover side(is the comment problem) of the exhaust side. After replace the valve cover gasket and road test the car on the freeway for 30 minutes. The service engine light come on and put the scanner. The code was 2A82 VANOS Intake (P0012 Camshaft position - Timing over-retarded (Bank 1) (PLAUS)). I erase the code and test drive the car the light came on again same code. After that we put a lad scope to check the camshafts and crankshaft single they good.  We check on the timing mark first everything was on the right position and put the smoke machine to see if any vacuum leak and there was no vacuum leak. we also do a redactor pressure test and the test came out good. Still looking for the problem.
