Why is the fan running in my Jaguar?
Lift off the engine cover & touch one of the charge coolers, it should be noticeably cooler than the alloy intake tube that runs between the charge coolers, if it’s the same temp or warmer then i’d be looking at the intercooler coolant circuit and the electric pump. But the thermostat should also be on the list.
How to check engine temp on Jaguar X350?
TonyXJR bought a thermostat kit and changed it quite successfully. Also 57jam89 in the S Type forum describes a process for checking engine temp using the button on the indicator stalk, i’m going to see if that works on the X350. After i’ve checked I have a button on my indicator stalk!!!!!

How can I change the oxygen sensor on my car?
Locate the oxygen sensor on your vehicle by looking for a part that looks like a spark plug that sticks out from the exhaust pipe. It will have an electrical connection attached to it. Disconnect the electrical connection on the oxygen sensor. Use a flat tip screwdriver to push in the tabs and pull the connection apart.
What are the different types of oxygen sensors?
There are two different types of oxygen sensors, sensors with one wire and sensors with three wires. The three wire sensors have a built-in heating element that brings the sensor up to operating temperature quickly.
When do you Know Your oxygen sensor is bad?
The first indication of a problem with your vehicle’s oxygen sensor is often when the “check engine” light comes on. Failing sensors cause jerky movements, trouble starting, and reduced fuel efficiency if they aren’t replaced. Oxygen sensors are necessary for vehicles to combine the proper ratio of gas and oxygen into fuel.
What happens if your oxygen sensor is bad?
A bad oxygen sensor will continually tell the computer that the engine is too lean, and the computer will respond by sending more fuel.
How often should I replace my Oxygen sensor?
It’s a bad thing. According to Jaguar and the other auto manufacturers, the oxygen sensor should be replaced every 30,000 miles to ensure troublefree performance. There are two different types of oxygen sensors, sensors with one wire and sensors with three wires.

Is it bad to have an oxygen sensor in your car?
This is bad, not only for fuel economy and emissions, but a rich mixture will eventually burn out your catalytic converters, possibly causing a fuel fire inside the exhaust system, which can then spread to the rest of your car. It’s a bad thing.
What happens when a knock sensor goes bad?
It detects any engine noises caused by detonation — when fuel explodes in an engine’s cylinder– and adjusts ignition timing accordingly. If the knock sensor malfunctions, detonation is not properly regulated and major engine damage can occur.
Can a bad knock sensor cause a check engine light to flash?
Usually a bad knock sensor will trigger the “check engine” light to flash on your vehicle’s dashboard. Sometimes, using cheap gasoline causes detonation and triggers the power train module — the engine’s main control board — to wrongly diagnose the knock sensor and send a false malfunction message via a check engine light.
What happens when a shop knock sensor fails?
A failed knock sensor will register a trouble code and illuminate the Check Engine lamp (CEL), although some engines will require multiple failure cycles before storing a code. Knock sensors don’t fail often, but if you suspect this problem, it’s one you need to move on quickly to head off engine damage. SHOP KNOCK SENSORS.

When was the O2 sensor first installed in a car?
O2 sensors, also called lambda sensors or oxygen sensors, measure the proportion of oxygen in vehicle exhaust. The sensors were first installed in vehicles in the 1970s, when the Environmental Protection Agency introduced exhaust regulations.
What are the relays on a Jaguar S-type?
Diesel – Engine management system relay (2004) 2006-2008: Heated Exhaust Gas Oxygen sensors, ignition EMS relays. Diesel/petrol – EMS relays, Supercharger water pump relay. 2004-2005: Petrol – Ignition coil on plugs supply, capacitor, HEGO Relay coil.
What is the difference between front and back O2 sensors?
Most O2 sensors have an internal heating element so that they can reach the required temperature more quickly and remain there even during idling, when exhaust temperatures can drop below the threshold for oxygen sensor function. Front O2 sensors analyze the exhaust coming directly from the engine.

How does the engine control system work in a Jaguar?
Two throttle engines (V12) use one or two manifold absolute pressure sensors (MAP Sensor), which sense engine intake manifold absolute pressure. The sensors connect to the intake mani- folds downstream from the throttle valves so that manifold absolute pressure changes (opening / closing throttle valve) act on the MAP sensor element.
Why is my Jaguar XJ6 Series III not starting?
In an early incidence, trying to ascertain my no-start problem, I found the Temperature Sensor on the top of the water manifold to have a defective connection. While the car was running, I fiddled with various wire connections to see if a bad electrical connection elsewhere was the culprit.
Where is the missing pulse sensor on a Jaguar?
The sensor is located either on the timing cover or at the rear of the engine. The reluctor, mounted on the crankshaft, has a number of “teeth” with one or two removed to form a gap, which creates a missing pulse. The missing pulse allows the ECM to determine the crankshaft position for fuel injector pulse synchronization.
What kind of engine does a Jaguar XJ6 have?

What happens when a mass airflow sensor is faulty?
The air mass information is necessary for the ECU to correctly balance and deliver the correct amount of fuel to the engine. When a vehicle’s mass airflow sensor is faulty or defective it can cause a variety of problems, and usually results in very poor performance from your engine.
What does trouble code p0100 mean on MAF sensor?
The mechanic will use a scan tool to check what trouble code is retrieved. The trouble codes from P0100 to P0104 all indicate that something is wrong with the mass air flow sensor. The trouble code P0171 and P0174 are also caused due to a damaged or faulty mass air flow sensor.
Why is my Jaguar X type MAF sensor not working?
If so plug it in and see if the figure for the MAF is static or changing. If it’s a 2.0d the issue could be with broken wiring at the plug. Sorry, it’s a 2005 2L Diesel.. It has returned a fault code P0100 indicating MAF circuit failure.
What are the symptoms of a bad air flow sensor?
The symptoms of a bad mass air flow sensor include low engine power, poor fuel economy, an engine that won’t start, a check engine light on the dash and a gas smell from the exhaust fumes. A bad mass air flow sensor is often the likely culprit if your car isn’t running as it should.
Can a bad mass air flow sensor trigger a check engine light?
Bad mass air flow sensor with no check engine light? Sometimes a mass airflow sensor can start to fail and even trigger engine error codes such as P0101 and P0102, without triggering a check engine light. There must be a problem with the mass airflow sensor circuit for the check engine light to illuminate.
What do you need to know about oxygen sensors?
It’s got four oxygen sensors. You really need to get it plugged onto a code reader to see which code it displays to point you in the right direction. A garage will do it or there are DIY devices on ebay from around £20. 4 oxygen sensors???
Where are the O2 sensors on my car?
