It is the code for the TPS Throttle position sensor
Fuel Fail 47 Idle speed contol valve - coil 2: Open or short circuit.
This means Idle speed control motor (ISC) or valve
Fuel Fail 37 is either a fault with the EGR Valve or its Solenoid
im 99.9% sure its for the oxegen/lambert scensor. mine wouldnt start today but i managed to get it going and i think i need to replace the scensor. the discription of what the a faulty scensor does and what my car is doing match so it must be that.
Evaporative canister purge control valve circuit fault
Just Push down on it, it will pop up
Ignition Amplifier Failure
I own a 91' XJ6 also and i believe when that code comes up it is as simple as your gas cap not being on all the way
low battery. had battery tested load type. faild replaced battery fix code 29 thank you
o2 sensor fuel too rich
In 1990-1994 XJ6 the VCM Code 44 is the code for the O2 sensor, either rich or lean exhaust has been detected and is causing the code to trigger. It could indicate a bad O2 sensor.
Fuel fail 39. EGR circuit. Faulty system operation. Is on my 90 xj6 as well- going to take EGR valve off and clean it- see what happens.
coolant temp sensor fault
Idle speed control valve coil 1 fault. Off voltage not less than 0.85 volts or on voltage not exceeding 12.25 volts.
Yes, the Jaguar XK8 does have a fuel pump.
2 things are common. Mass air flow sensors fail, fuel pump issues check fuel pressure first do it when vehicle is "acting" up. 35-42psi . have seen fuel pressure regulators fail pushing psi up to 60psi. too high
fuel 44 is heated oxygen sencer bank A other term lambda senser the jag has two.
the fuel pump is in the gas tank. located on the top of the tank. The relay in my 92 is under the hood, drivers side, right in front of the firewall, about 2 feet from the fender.
It could cause a failure. The line could be collapsing, causing no flow through it. This would cause a fail code.
The 2014 Jaguar XJ runs on flex-fuel (FFV).
Code fuel 1 would indicate Oxygen sensor. A good information source is the Haynes Manual Jaguar XJ6 1988-94. Good luck.
The fuel pump is in the fuel tank.
Not instead of fuel, no.
