P0011 CODE

[fishing1]

I have nissan maxima 2002, with P0011 code, ivt control valve or solenoid, where is it on the car, and about how much does it cost

AFAIK, this is not a common problem with Maxima. Using signal from the Crankshaft position sensor, Camshaft position sensor, coolant temperature and engine speed, the ECM control the IVT control solenoid valve to adjust the intake valve open/close timing. Problem with Bank 1 (cylinders 1-3-5) near firewall) IVT will trigger DTC P0011 (Bank 2 for cylinders 2-4-6 near the radiator will trigger P0021).

It will help you a lot if you download a copy of the FSM and go to EC chapter for the diagnostics. I simplified the procedure from the FSM to help you isolate the problem.

Each bank has a separate IVT control solenoid valve - Bank 2 solenoid is close to the oil filler while Bank 1 solenoid is more towards the firewall. Locate the Bank 1 solenoid valve, connectors F58 and F197. Pin 2 has a R/Y (red/yellow) wire while Pin 1 has a red wire. Use contact cleaner to clean the connectors and then check the condition of the pins/sockets. Check the resistance of the solenoid valve - across pins 1 and 2 must be 7 to 7.7 ohm at 68F ambient temp. If not, you have a defective solenoid valve. Pins 1/2 to ground must be an open circuit. If Ok, set ignition to ON (do not start) and check pin 2 voltage must be the same as battery voltage. If not, you might have a blown fuse (15A, 5B) or an open circuit between the ECM relay (E32) and the solenoid valve.

To reset the ECM, disconnect the battery (ground side) for at least 30 seconds.

The rest of the diagnostic procedure is complicated and would be difficult to do without the FSM. It requires checking continuity to the harness, condition of Crankshaft and Camshaft position sensors, etc.

Good luck.

i have an 03 se and it is showin oth p0011 and p0021 so it mst be pretty common. what is fsm also LOYSTOCK ?

FSM is the factory service manual.The FSM for your '03 is here. Should cover the '02 as well, as the two years were basically identical.

thanks minister i think mine is the vehicle speed sensor bc the digital speed is stuck at 28 mph. all the other symptoms of those codes the is not doin but that one. so im not goin to worry about that lol
