P0725 Nissan Code - Engine Speed Signal
Quick Answer
The Engine Control Module (ECM) monitors the engine speed through the Crankshaft Position (CKP) sensor with the engine running, and send a signal to the Transmission Control Module (TCM). Common causes include Faulty Crankshaft Position (CKP) Sensor, Crankshaft Position (CKP) Sensor harness is open or shorted, Crankshaft Position (CKP) Sensor circuit poor electrical connection. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

oye mi auto me marca los 2 codigos el p0335 y el p0725.. y anda muy pesado para acelerar se nota que tiene muy poca potencia.. y tarda bastante para prender.. tengo que darle mucha marcha para prender... solo esos 2 codigos me salen con el scaner.. crees que poniendoselos se componga?? y cual de los 2 debo poner primero?
es un altima 2003 2.5l aut. -
El que creo que esta dando mas problem es el Crankshaft Position Sensor ( http://www.autocodes.com/p0... ). Recomiendo que comiences cambiando ese sensor primero.
-
nunca se me ha apagado solo... es solo que acelero y sin fuerza y dura varios segundos para prender ay veces que ocupo 2 o 3 intentos .. y el scanner solo salen esos 2 codigos.. me arriesgare mañana y cambiare ese haber que pasa.. gracias
-
muchisimas gracias.. me ahorraste mucho dinero.. le puse el sensor a mi carro y quedo como de agencia.. ya lo camine mas de 100 km y no encendio SES .. me querian cobrar 5000 pesos (300 dlls).. y solamente gaste 30 dlls (550 pesos).. yo mismo puse el sensor y quedo como nuevo.. muchas gracias por tu pagina.. si puedo hacer algun donativo dime a donde.. thanks a lot

Que bien que se arreglo el problem. Me ayudaria si recomienda mi sito a sus amigos. Gracais.

Mi auto arrojó 2 codigos P1722 Y P0725 es Nissan Altima V6 3.5 Transmision CVT 2008; Dejó de hacer cambios, se quedó en 5ta velocidad...Ni con el modo MANUAL respondía hasta que hice alto total, en ese lapso perdió bastante potencia, Me detuve, apagué el motor realizé un chequeo visual, reanudé mi marcha y todo se normalizó ¿Que opciones me das para resolver este problema?¿Porque se ocasiono? Gracias.
-
Cuantas veces a pasada el problema? Te recomiendo borrar los códigos y esperar si le salen otra vez. También inspecciona las llantas, en algunos caso el código P1722 sale porque uno de los sensores de las ruedas (ABS/VDC wheel speed sensor) no está leyendo correctamente. Si las llantas estan bien, es posible que el problema sea el Crankshaft Position Sensor (mira el video arriba)
-
Solo 1 vez, lo que pasa es que nunca lo había corrido a 200Km/h ¿Necesito volver a hacer la prueba a esta velocidad?
Saludos -
Tengo un Nissan 2008 tiene speed sesor y transmission range sensor digame esta mal la transmisión o es los sensor
-
Hola Ethan, a mi me pasó exactamente lo mismo (con el mismo model de carro), pero solo me arrojó el P0725, y después de detenerme siguió el problema hasta que se enfrió el carro. Pudiste resolver el problema? O reproducirlo? Necesito sacar el carro a carretera pero si me va a volver a pasar lo mismo no se que hacer.
-
This is right for a Nissan xtrail 2.5 petrol uk spec.
Q. Can you swap the CKP with the CMP to prove the fault is with the sensor. Just out of curiosity.
Thanks peoples. -
Unfortunately I have never done that, not sure if works and there is no information in the service manual if the sensors are compatible.
-
Tengo un nisan sentra 2008 me ha salido este codigo 2 veces que puedo hacer, tiene un ruido extra?o la transmicion.
-
Si tiene un ruido, entonces tiene un problema mecanico en al transmision. A este punto le recomeindo que contacte un mecanico para que le revise la transmision.
-
Me sale el P0725 y le cambie este sensor y el problema no se soluciona prende no tiene fallo pero cuando voy en marcha el carro no tiene fuerza y empieza a fallar el fallo empezo cuando el carro disminuia velocidad en las cuestas y no pasaba de 20 millas ahora el problema es q ha perdido la fuerza y no puedo acelerar en marcha mas.
-
que tal amigo Oscar solucionaste tu falla? a mi me pasa igual y no lo he encontrado

I have a 2011 nissan altima (2.5s, 102K miles, original owner) that recently had a check engine light come on. A couple of days later it wouldn't start. I checked fuses, i checked that the engine was firing, I checked that I had gas, and I removed the backseat to check the fuel pump. I can hear the fuel pump working. I popped out the connector and reconnected it. I tried getting a reading from it but I wasn't able to really. So I plugged the connector back in and decided to try starting it and it did, However, it continues to have the check engine light (Which seems logical since I didn't really do anything). Since it was running, I took it to the local parts store and they read the codes for me.
There was 14 total, but these were the only unique ones: p1701, p1705, p0826, p1722, p0725, p0463, p0183, and p0101.

I have a 2011 nissan altima experiencing the same problem (sporadic stalling). I replaced the crank position sensor, sensor assembly magnet, and cam shaft position sensor. drove it for about 150 miles over a two week period with no problems. My daughter drove it and it stalled. it showed the following codes: p0725, U1000, P1705, P0826. the car shifts well, no problem there, is now have a rough idle. Any suggestions, its got about 125,000 miles??
-
The P0725 - Engine Speed Signal code on your 2011 Nissan Altima indicates that the ECM (Engine Control Module) is not receiving a proper engine speed signal from the crankshaft position sensor (CKP). Since you've already replaced the crankshaft position sensor, camshaft position sensor, and sensor assembly magnet, but the issue persists, let's analyze the additional codes and possible causes.
Understanding the Additional Codes:
-
P0725 - Engine Speed Signal
- The ECM is not receiving a consistent RPM signal, which can cause stalling, rough idle, or even failure to start.
-
U1000 - CAN Communication Error
- This means the ECM is having trouble communicating with one or more control modules (e.g., TCM, ABS, or BCM). This could be due to wiring issues, a failing ECM, or a loose connector.
-
P1705 - Throttle Position Sensor (TPS) Circuit Malfunction
- The TCM (Transmission Control Module) uses the TPS signal for shift control. A failing TPS or wiring issue can lead to rough idle and stalling.
-
P0826 - Up/Down Shift Switch Circuit
- This usually relates to the manual shift mode (paddle shifters or manual mode on the gear selector) but shouldn’t affect idling or stalling.
Potential Causes of the Stalling and Rough Idle:
-
Crankshaft Position Sensor Circuit Issue
- Even though you've replaced the sensor, there could still be:
- A damaged wiring harness leading to the sensor.
- Poor grounding or corroded connectors at the CKP sensor or ECM.
- Aftermarket sensors sometimes cause issues. If you used a non-OEM crankshaft position sensor, it might not function properly. OEM sensors are recommended.
- Even though you've replaced the sensor, there could still be:
-
Throttle Position Sensor (TPS) or Electronic Throttle Body Issue
- The P1705 code suggests the TPS may not be sending the correct signal.
- A dirty or failing throttle body can cause rough idle and stalling.
- Try cleaning the throttle body and performing an idle relearn procedure.
-
ECM or Wiring Problem
- The U1000 code suggests a possible ECM communication fault.
- Inspect all ECM-related wiring harnesses, especially near the battery, fuse box, and engine ground points.
-
Battery or Charging System Issue
- Low voltage from a weak alternator or battery can cause erratic sensor readings, leading to multiple codes.
Recommended Steps to Fix the Issue:
-
Check the Wiring for the Crankshaft Position Sensor:
- Inspect the harness and connectors for damage, corrosion, or loose pins.
- Test continuity between the CKP sensor and ECM using a multimeter.
-
Inspect and Clean the Throttle Body:
- Remove and clean the throttle body using throttle cleaner (do not force the throttle plate open).
- Perform a throttle position and idle relearn after cleaning.
-
Check the Battery and Alternator:
- Test battery voltage (should be 12.6V+ when off, 13.8V-14.5V when running).
- If the alternator is weak, replace it.
-
Clear the Codes and Perform a Test Drive:
- Use an OBDII scanner to clear all codes after checking wiring and cleaning components.
- Drive the vehicle and monitor for returning codes.
Final Steps:
- If the P0725 code returns, focus on the crankshaft sensor wiring or try an OEM sensor.
- If the P1705 code remains, the throttle position sensor (TPS) or throttle body may need replacement.
- If the U1000 code persists, you might need a mechanic with a Nissan scan tool to check ECM communication.
