Two codes coming up on car even after fixing alot on car now need to figure out low cost ways to fix P0744 & P0722 code issues spent 1,800 on car & have spent 1,400 already in parts & labor.


you need a better mechanic that traces ALL of the possibilities of each code, not just read the code and trow in a part hoping that it's fixed ~ it can be wiring as well, not just plug in a new part as mentioned on the 2nd trouble code to the vehicle speed sensor

P0744 Torque Converter Clutch Circuit Intermittent


P0722 Output Speed Sensor No Signal

the first of the 2 looks to be more intensive to trace and find out the problem & the 0722 is the easier job for an intermediate mechanic to trace the wiring for continuity

94 nissan altima won't start and iddle after cleaning IACV valve


An IAC (idle air control) motor is designed to adjust the engine idle RPM speed by opening and closing an air bypass passage inside the throttle body. The cars computer or PCM (powertrain control module) receives information from various sensors and will output signals to adjust the idle air control motor in or out to adjust engine idle speed by controlling engine idle air. An idle air control motor can fail one of two ways, either the motor short circuits and stops working or the motor will develop high resistance and cause the idle air control motor to react slowly, either failure can cause the engine to stall at idle. When a trouble code scan is performed it sometimes won't always detect a failed or weak idle air control motor.

01 Nissan Altima check engine light code p0740


Classic engine miss. The cause might be a faulty injector, or more likely an issue with ignition. Start it at night in the dark and look for arcing- that is the area to start. Plug wires and ignition components.

My service engine soon light is on and it reads that the engine speed signal circuit is the problem, what should I do!


This is normally caused by the Crank Sensor. The Engine Speed signal is given by the Crank sensor, not the vehicle speed sensor. Most people get confused and replace the speed sensor instead.

So to resolve your problem you will need to replace the crank sensor. The engine speed sensor code is always related to the crank sensor failure.

Thanks Jay!

2005 nissan almera,1.5letre.. fault code po725


P0725 NISSAN - Engine Speed Signal

The P0725 Codes is triggered when TCM does not receive the engine speed signal from ECM.

The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send signal to the Transmission Control Module (TCM).

Symptoms:
- Engine Light ON (or Service Engine Soon Warning Light)

Possible causes:
- Open or shorted CKP sensor circuit condition
- Poor CKP sensor electrical connection
- Check communication error between the ECM and TCM
- Failed CKP Sensor

Possible solution:
Very common problem with Nissan vehicles, usually replacing the Crankshaft Position sensor takes care of the problem.

Keep us updated.

You should stop by your local Auto Parts store and see if they can check your service engine light with a code scanner. Some places do it for free. This could point you to a better direction.
