Nissan exterra: have a 2006 nissan exterra. service engine

Customer Question

have a 2006 nissan exterra. service engine light has been on for over a year. our mechanic kept testing & guessing & no results. finally today we bro& he said there was sludge in the engine. we get regular oil changes. the tech said the timing sprocket was stuck at 17* and it would cost $4000.00 to change all the timing componants with no guarantee that the vehicle would be ok after the repair. does this sound right, or is this a hoax? please let me know. thanks, Charlie

1. check for power on the Red/Yellow wire bank 1 and an on/off signal at 2000 RPM on the Red wire. On bank 2, check the Red wire for power and the Green wire for the on/off signal when the engine is revved to 2000 RPM. 2. If the signal is good, then the Engine Control Module (ECM) is trying to control the cam timing. Manually ground the signal wires to see if a change in the way the engine idles can be heard. If so, the solenoids are working. If not, the solenoids could be stuck. 3. The resistance of the IVT solenoids is 7.5 ohms at 70°F.We have experience with this code for this vehicle. We had to Replaced Intake Valve Timing (IVT) Control Solenoid Valve(s) because it was stuck. This job does not take $4000. It is about $1400.Please rate me positive, thank you!
