Introduction

Ford Fiesta IV Phase 2 1.3i 60cv 1999-2002 Here we will replace the lambda sensor, as it is a fragile part, be careful when handling it. Also let the engine cool down before any intervention to avoid the risk of burns because this sensor is located on the exhaust manifold.

  1. 
The lambda probe is located on the exhaust manifold at the front of the vehicle

Follow the cable to locate its connector

  2. 
Disconnect the probe connector, to do this press the tab then pull the connector

It is advisable to wait until the engine has cooled and to wear gloves when removing the probe.

Unscrew the probe using a size 22 open-end wrench and remove it from the collector

  3. 
Check that the new probe matches the old one:

At the thread diameter level

At the connector level.
    • Check that the new probe matches the old one:

    • At the thread diameter level

    • At the connector level.

    • It is possible to buy generic lambda sensors to rewire, it just requires a little more work.

    • The lambda probe is a sensitive part so avoid any shock when handling it.

  4. 
Start by cleaning the exhaust manifold threads using a brush.

Place the new lambda probe on the manifold and screw it in by hand, then finish tightening moderately with a 22 mm flat spanner.

If you have a torque wrench with a size 22 open-end bit, you can tighten it to the 4.2Nm torque recommended by Ford.

This is a good tutorial.

Having had two identical Endura 1.3 60hp petrol cars (a restyled 2001 Fiesta IV contact scrapped at 208,319 km for a coolant leak on the water box on the intake manifold) and a non-restyled 1998 Fiesta IV Studio which still runs and has 220,000 km to date, and having never changed this Lambda sensor on these two cars, I would like to know how you diagnosed that it was out of order. Using a diagnostic case? Or a vehicle fault code reading kit?

On the other hand, on both vehicles, I had to change the ignition coil block which curiously “gave up” around 180,000 km on both vehicles and which generated poor ignition on certain cylinders. (end of life of this part)

THANKS

Sincerely
