Where is the EGR valve on a 2002 Ford Focus?

Where is the EGR valve on a 2002 Ford Focus?

Open the hood of the Focus. Notice the EGR valve, which is a circular valve located on the engine intake manifold. It is secured in place by bolts.

What does the code P1401 mean?

Error Code P1401 is defined as DPFE (Differential Pressure Feedback Sensor) Error. This error code is a manufacturer-specific trouble code, meaning it does not apply to all vehicles makes. Rather, it applies only to specific vehicle makes, such as Ford and Hyundai.

What will happen if I remove my EGR valve?

Removing the EGR valve will certainly remove a component that requires regular maintenance, but it will make your car less efficient, as well as committing a detrimental offence both to the environment and to other drivers and road users.

What happens if you bypass the EGR valve?

When the EGR passageway becomes blocked off it keeps exhaust emissions and air from circulating in the engine, causing a suffocating condition. The engine idle will be rough, frequently stumbling and unable to hold a steady idle rpm. The rpm may be sporadic, raising and lowering randomly.

What causes P0401 code?

Code P0401 is triggered when the EGR temperature sensor does not see enough of a temperature change when the EGR is commanded to open. These sensors tend to get a lot of carbon buildup that causes them to lose sensitivity to the heat from the EGR gases.

How much does it cost to diagnose a Ford P1401 code?

Please try again later. The cost of diagnosing the P1401 FORD code is 1.0 hour of labor. The auto repair’s diagnosis time and labor rates vary by location, vehicle’s make and model, and even your engine type. Most auto repair shops charge between $75 and $150 per hour.

Can a P1401 code on a Ford EGR valve be fixed?

The recommended repair for a P1401 code is to replace the DPFE sensor with a new one. Ford offers an upgraded DPFE sensor for most models (part number 4U7Z-9J460-AA) that is reportedly higher quality than the factory sensor it replaces. If replacing the DPFE sensor does not clear the P1401 code, the problem may be in the EGR valve itself.

Why does my dpfe sensor not clear the P1401 code?

If replacing the DPFE sensor does not clear the P1401 code, the problem may be in the EGR valve itself. Thus, the next step is to checked, clean, and/or replace the EGR valve along with its input tube.

What does the P1401 code on a TSB mean?

The TSB is merely documentation of a known issue and proper diagnoses and repair procedure. The exhaust gas recirculation (EGR) valve has a differential pressure feedback sensor (DPFE). When this sensor goes bad or fails, it can trigger a P1401 and several other related codes (P040# variants, usually) and create a rough idle.
