P0725 CODE HOW TO FIX

P0725 - Engine Speed Sensor Input Circuit Malfunction

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

P0725 JEEP Description 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). Could be a faulty crank sensor or wiring problem.

Hi there:

DTC P0725 - ENGINE SPEED SENSOR CIRCUIT

When Monitored: Continuously after a ignition key is turned from the OFF to RUN

position and/or key is turned from the CRANK to the RUN position.

Set Condition: The code is set when the engine speed sensed by the Transmission Control

Module (TCM) is different than the engine speed reported by the Powertrain Control

Module (PCM) over the Communication Buss.

POSSIBLE CAUSES:

CHECKING SYMPTOMS AND POSSIBLE CAUSES

LOW BATTERY VOLTAGE

BAD CONNECTIONS AT VARIOUS CONNECTORS

CRANK POSITION SENSOR SIGNAL OPEN

CRANKSHAFT POSITION SENSOR GROUND CIRCUIT OPEN

TCM CRANK POSITION SENSOR MONITORING DEFECTIVE

Hope this helps.

Without knowing make or model Po725 is a Chrysler code for Engine Speed Sensor Circuit
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 When is the code detected- The P0725 Codes is triggered when TCM does not receive the engine speed signal from ECM. Chrysler description- 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

Engine size? 2.7L????Are you sure the timing chain is OK?

Best to have a transmission place work on this.
Here are the meaning of the codes:
P0700 Transmission Control System Malfunction
P0740 Torque Converter Clutch Circuit Malfunction

It maybe cheap to fix like a bad sensor. Or it maybe something serious going on. Best to have a transmission shop check it out.
Good luck.

i have this same problem with my pt cruiser did you ever figure out what was wrong with it
thanks let me know my email is [email protected]

replace the input speed sensor to transmission and the wiring pigtail all are available at your chrysler dealer take your vehicle registration in to the parts counter so they have your vin # to get the right part and it is the front of trans by fluid linres to radiator.

off the top of my head I am not sure w\hat exactly that code is although I do now it sound familiar. Most code tat are p one codes are usually more of an electrical problem or even a sensor. For that code all I can say right now is possibly a speed sensor issue or wiring
