P0725 on Nissan
Engine Speed Input Circuit Malfunction
P0725 on Nissan vehicles indicates engine speed input circuit malfunction. Au7o has documented this code across 1 Nissan model — most commonly on Altima. This generic powertrain code means the transmission control module or PCM is not receiving a reliable, rational engine-speed (or input/turbine) signal from its speed sensor. The computer compares this rotational-speed input against other sensors to manage shift timing and torque converter lockup, and it sets the code when that signal goes missing, drops out, or reads illogically. It usually points to a sensor or wiring problem in the speed-input circuit rather than an engine failure itself. Typical repair costs on Nissan range from $150 to $600, depending on the specific model and root cause.
Common Causes of P0725
- •Faulty engine/input speed sensor
- •Damaged, corroded, or loose sensor wiring or connector
- •Low or dirty transmission fluid
- •Open or shorted circuit between sensor and PCM/TCM
- •Poor ground or power supply to the sensor
- •Internal transmission damage affecting the sensor
- •Faulty PCM/TCM (rare)

- Crankshaft and Camshaft Position Sensor Failures Causing Stalling or No-Start2002-2012
Altimas in this period frequently suffer from failing crankshaft position sensors and camshaft position sensors, especially on the 2.5L and 3.5L engines. Owners report intermittent stalling at stops or while driving, extended cranking, sudden no-start conditions, and check-engine lights. Nissan issued service information and many owner reports describe repeat failures with cheap aftermarket sensors.

What does P0725 mean on Nissan?▼
P0725 stands for "Engine Speed Input Circuit Malfunction." This generic powertrain code means the transmission control module or PCM is not receiving a reliable, rational engine-speed (or input/turbine) signal from its speed sensor. The computer compares this rotational-speed input against other sensors to manage shift timing and torque converter lockup, and it sets the code when that signal goes missing, drops out, or reads illogically. It usually points to a sensor or wiring problem in the speed-input circuit rather than an engine failure itself. On Nissan specifically, this code is documented across 1 model.
What causes P0725 on Nissan vehicles?▼
Common causes on Nissan: Faulty engine/input speed sensor, Damaged, corroded, or loose sensor wiring or connector, Low or dirty transmission fluid, Open or shorted circuit between sensor and PCM/TCM, Poor ground or power supply to the sensor.
