Test Description The numbers below refer to the step numbers on the diagnostic table. 2. Allow the engine to cool before performing this test. If the sensor is at the operating temperature, the HO2S voltage will stay high or low. If the HO2S voltage stays between 300-700 mV this indicates the HO2S heater is inoperative. 3. If more than one HO2S DTC is set, this is a good indication that the HO2S fuse is open. Test all the related circuits going to all the heated oxygen sensors for a short to ground. If you cannot locate a shorted circuit, it may be necessary to disconnect each HO2S one at a time to locate a shorted sensor. 4. This step determines if an ignition positive voltage supply is available at the sensor.

When the engine is first started, some vehicles may exhibit a loud ticking noise from the variable valve timing
(VVT). This is caused by the lock pin of the variable valve timing actuator not fully engaging. Heat treatment has
now been added around the hole of the variable valve timing rotor lock pin to prevent this from happening

BAT is pleased to be able to offer this line of components for the U.S. specification “Merkur” XR4ti, Scorpio and the other European models of Sierra lineage. European Sierra models have been manufactured since 1982 and include
two versions or body styles. We will concern ourselves with the Mark 1 as it is more similar to our U.S. version. The high water marks of the MK1 series are the XR4i and the Sierra Cosworth and R/S 500 models. From the exterior, XR4i is very similar to the U.S. Merkur XR4Ti in overall looks. However, under the hood it is powered by a 2.8L V-6 engine
