I have check engine diagnostic code c1000e on Nissan Altima 2002. what does the code mean? The vehicle drives and reverses but stuck on D4. The check engine light is on and the OBD2 test shows code c1000...


hi, C1000- Engine; CAN Communication Circuit.

That and maybe water got into a connector. Maybe the AWD connector. Be sure to read the LAN System section in the SM. and the TF transfer section. Sounds like the CAN line going to the AWD clutch got shorted or opened. Problem is the full diagnostics need the Consult 4. I think may be it can help you.

That is pure nonsense. The PO 507 appears to be Idle Air Control System

Look over the car yourself

Make sure the Air Filter cover is on correctly and all duct work to the Throttle Body is in place and tight and you have no other vacuum hoses off.

You never need a Dealer. All you need is good professional scanner and up todate software.

Hi i have 02 altima 3.5 v6 who have check engine light with code p1800 what is manufactured transmission control can anyone help me what that means?


You may want to have someone else take a look at it. The Nissan P1800 trouble code is not a transmission control problem. It is described as follows:

Trouble diagnosis name: VIAS control solenoid valve circuit.
Component Description:
The VIAS control solenoid valve cuts the intake manifold vacuum signal for power valve control. It responds to ON/OFF signals from the ECM. When the solenoid is off, the vacuum signal from the intake manifold is cut. When the ECM sends an ON signal the coil pulls the plunger downward and feeds the vacuum signal to the power valve actuator.
DTC detecting condition:
•An excessively low or high voltage signal is sent to ECM through the valve.
Possible cause:
•Harness or connectors (The solenoid valve circuit is open or shorted.)
•VIAS control solenoid valve

Check your vacuum hoses to make sure they are in good shape and are securely attached Aslo check the wiring harness is ok and securely attached as well. If they are, you’ll probably need to replace your VIAS. It's right next to the throttle body.

Nizzan 02 Black smoke coming out tailpipe and consumption of oil


Black smoke is caused by excess fuel that has entered the cylinder area and cannot be burned completely. Poor fuel mileage is also a common complaint when black smoke comes out of the tailpipe. Black smoke out the tailpipe is the least cause for alarm. Excess fuel will usually effect engine performance, reduce fuel economy, and produce a fuel odor. Some of the causes of excess fuel are a carburetor that is out of adjustment, a faulty fuel pump, a leaky fuel injector, or a faulty engine computer or computer sensor. If black smoke is present, check the engine oil to make sure excess fuel has not contaminated it. Do not start the engine if a heavy, raw fuel smell can be detected in the engine oil.

2003 Nissan Altima 2.5S, Check Engine Light Problem.


this problem could be caused by the mass air flow censor, i had the same problem with my car. it is really pricey at the dealer so you might want to check elsewhere for this part. I found one at a scrap yard for 85% less that the dealer and i also got life time warranty, the dealer does not offer any warranty on this part.
