P1700 - FAULT CODE - OBD2

P1700 Code failures by brands

P1700 FORD, LINCOLN, MERCURY: TRANSMISSION SYSTEM PROBLEMS

Description of DTC code P1700

The automotive transmission adapts the engine output to the drive wheels. In internal combustion engines, it is necessary operation at a relatively high rotational speed, which is unsuitable for slow travel, starting, and stopping. The transmission reduces the higher engine speed to a lower wheel speed, thereby increasing engine torque in the process.

The transmission is usually connected to the engine crankshaft using a clutch or fluid coupling. The output of this is transmitted through the driveshaft to one or more differentials that drive the wheels. Although a differential also provides a gear reduction, its primary function is to allow the wheels at each end of an axle to turn at different speeds, which is necessary to prevent wheel slippage during turns.

The PCM (Powertrain Control Module) continuously monitors the TCM (Transmission Control Module). In case the TCM detects an internal transmission problem, the diagnostic code P1700 OBDII will be set.

Symptoms of fault code P1700

Check Engine lamp ON.
Problems during gear changes.
Driving difficulties.
Lower fuel consumption.
Transmission blockages.

Causes of OBD2 P1700

The DTC P1700 OBD2 is set by one of the following reasons:

Other TCM-related DTCs may be stored.
An internal component of the transmission may be in poor condition.
The direct clutch of a steering system may be faulty.

Possible solutions of the DTC code P1700

Steps to solve the P1700 OBDII fault code:

Consult the TSB (Technical Service Bulletins).
Check if other DTCs are set. If so, diagnose and repair them.
Checks the condition of the one-way direct drive clutch. Consult the steps to diagnose this component. If you discover inconsistencies, make corrections.
