Check engine light on code p1800 amd p650 is it

That is not a valid code for your car. If it is P1800, that is the code for a transmission control module Power Control Relay Circuit Open which can lead to harsh shifting (among other things).

yes, there is and a good parts store clerk should be able to show you your options

have you done anything to fix the fault that caused the code
if not then logically the code will reappear until you go

Clean or replace the mass air flow sensor , clear codes and road test

code p1800 refers to engine torque signal ---malfunction===causes--wiring ---TCM (transmission control module).
replace the TCM

the code is for engine torque signal malfunction.its either a short to voltage or ground in between engine computer and transmission computer. or a bad trans computer [tcm] manuel says check for shorts or bad connections at the connectors from ecm to tcm then states if no wire problems found then try a new tcm and if problem goes away then install new tcm.i know those instructions are lame but it comes from the kia service manuel. there are no tsb or recalls listed for that code. so i would recomend take to dealer because they would have a known good tcm to try.plus if you bought the car new then the 10 year 100,000 mile warranty may still be in effect beings how its a powertrain issue so if less than 100,000 miles and you bought it new it wouldnt hurt to ask them if it might be covered

call back your local autozone. they should have given you a print out of possible solutions and they could have told you what to try

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.
