Where is the heater control valve sensor located on a 2005 jaguar s-type

the water heater control valves are front right down low behind the radiator and are electricaly operated ,the AC pipe that runs under the engine but above the sub frame could be corroded out as this is a common fault with these cars ,also the electrical solonoids that shut off the heaters can corrode up as well but i have known them to stick open.

Jaguar S-type 2000 fabrication year is equiped with:
1. Control system = Automatic temperature control
2. System layout = Single evaporator - dual zone
3. Refrigerant circuit type = Expansion valve
General information:
1. System control
1.1. Compressor operation controlled by refrigerant pressure sensor.
1.2. Compressor will not operate if refrigerant level is low!
1.3. System incorporates an A/C evaporator temperature sensor.
1.4. System incorporates an engine coolant heater regulator valve.
1.5. A/C control module incorporates self-diagnosis function.
1.6. The A/C control module fault memory can only be accessed and erased using diagnostic equipment connected to the Data Link Connector (DLC). See picture below:
1.7. Engine Control Module (ECM) incorporates A/C related trouble codes.
1.8. Malfunction Indicator Lamp (MIL) will iluminate if certain ECM faults are recorded.
1.9. The ECM fault memory can only be accessed and erased using diagnostic equipment connected to the Data Link Connector (DLC).
Trouble code Fault location
B1200 A/C control module - internal failure
B1251 In-car temperature sensor - open circuit
B1253 In-car temperature sensor - short to earth
B1255 Outside air temperature sensor - open circuit
B1257 Outside air temperature sensor - short to earth
B1259 A/C sunlight sensor - open circuit
B1261 A/C sunlight sensor - short to earth
B1262 A/C heater defrost flap motor - short circuit, open
circuit, short to earth
B1263 A/C heater fascia flap motor - short circuit, open
circuit, short to earth
B1264 A/C heater footwell flap motor - short circuit, open

B1676 Battery voltage - voltage too low / high
B1946 A/C evaporator temperature sensor - open circuit
B1947 A/C evaporator temperature sensor - short to earth
B1966 Heater output temperature sensor 2 - open circuit
B1967 Heater output temperature sensor 2 - short to earth
B2428 Heater output temperature sensor 1 - open circuit
B2429 Heater output temperature sensor 1 - short to earth
B2477 A/C control module - incorrect programming

P1647 is not nesesarily a fault with the sensor
Linear O2 Sensor Control Chip (Bank 2) could be faulty wiring or the ecu. Check the connections on the loom sides give the wires a gentle tug (don't pull them out) look for short circuits loom damage etc.

sound like air door stuck or actuator not working.look for loose or disconnected vacuum line.

look under the hood to be sure the heater lines are ok and hooked up also look for a shut off valve - some people shut off the heater core for the summer -
also check all fuses if it is not blowing or is an all electric control on the dash -

Probably the heater control valve, had same issue, started with one side not hot, then erratic, hot then cold while heat is set to hot, now both side are cold to lukewarm. diagnosed as heater control valve, common for jag s-types and x-types. located on the passenger side, down low the side of the radiator, it has several hoses into and out of valve, and a electrical connector.

how do i disconnect the wires on a heater control valve on a s-type jaguar with a 3.0 engine.

i am sure i posted this solution before the dual heater control valve is located looking front of car behind radiator left hand side low down very hard to get at probably better to get access from under car i have the same problem with my car i am trying to pluckup the courage to do it

IF IT TURNS OUT TOT BE THE CONTROL PANEL FOR THE A.C. THERE IS A PLACE THAT WILL REBUILD YOUR ORIGINAL PANEL - WITH A LIFETIME WARRANTY- AND A 4 DAY TURN AROUND FOR $99.00.

change O2 sensor their cheap enough ,heater valve not sure about ,seat and mirrors is either a fuse or a relay
