Question about 1989 Ford Crown Victoria

Thermactor air system inactive, right side: trouble code

I received a "thermactor air system inactive, right side" trouble code 44 on my 1989 crown victoria. No other error codes were output, including the identical left side trouble code. Air pump is operational, and high volume of air is output from diverter valve plumbing towards back side of engine. Piping runs from diverter valve to back side of passenger engine head, and subsequently to driver's side of engine to that head. I feel piping cannot be blocked, because same pipe feeds both sides of engine. I have not removed backfire valve because same valve feeds both heads, I suppose it could be part of problem, however i would think i would sometimes get trouble code to left side of engine. Should I remove backfire valve, and subsequently the plumbing to right head and look for some blockage? Is it possible there is another problem causing the trouble code? It is difficult to get to back side of engine. I don't want to be barking up the wrong tree after taking things apart.
Thanks.

SOURCE: engine overheats when heater pipes connected

I think you could be right about there being air trapped in the system.
Or the heater core(radiator) is plugged.
Either way you need a pressurized radiator coolant pump to put the coolant in without air being trapped.
Although,i have seen it done by jacking the vehicle up high enough that the radiator was now higher than the heater core level, and then the coolant was put in.
But this is dangerous to try.

you need to jack that side of the engine up. take the right side motor mount bolt loose then jack the engine up from underneath. be sure to use a block of wood or somthing so you dont bust the oil pan

Your car may need a new dis. Mogul, or coil you can test the coil and the Mogul seems to be part of a healthy tune up , it seems to be the number one cause of ruff running and eventually no start. depending on the miles and maintenance it could have play in the timing around 120,000. miles hope this helped , please feel free to ask if you need any further assistance. Thank You.

2007 ford taurus condensor fan not coming on with ac


Fan Control The PCM monitors certain parameters (such as engine coolant temperature, vehicle speed, A/C on/off status, A/C pressure) to determine engine cooling fan needs.
For variable speed electric fan(s):
The PCM controls the fan speed and operation using a duty cycle output on the fan control variable (FCV) circuit. The fan controller (located at or integral to the engine cooling fan assembly) receives the FCV command and operates the cooling fan at the speed requested (by varying the power applied to the fan motor).


EDGE/MKX, FIVE HUNDRED/FREESTYLE/MONTEGO, FUSION/MILAN/MKZ, CROWN VICTORIA/GRAND MARQUIS, TOWN CAR: FCV DUTY CYCLE OUTPUT FROM PCM (negative duty cycle) FCV Duty Cycle Command (NEGATIVE (-) duty cycle) Cooling Fan Response/Speed Greater than 0 but less than 5% Fan off, controller inactive Greater than 5% but less than 10% Fan off, controller is in active/ready state Edge/MKX, Crown Victoria/Grand Marquis, Town Car:
10% - 90% Edge/MKX, Crown Victoria/Grand Marquis, Town Car:
Linear speed increase from 30% to 100% Five Hundred/Freestyle/Montego, Fusion/Milan/MKZ:
30% - 90% Five Hundred/Freestyle/Montego, Fusion/Milan/MKZ:
Linear speed increase from 50% to 100% Greater than 90% but less than 95% 100% Greater than 95% but less than 100% Fan off
For relay controlled fans:
The PCM controls the fan operation through the fan control (FC) (single speed fan applications), low fan control (LFC), medium fan control (MFC), and/or high fan control (HFC) outputs. Some applications will have the xFC circuit wired to 2 separate relays.
For 3-speed fans, although the PCM output circuits are called low, medium, and high fan control (FC), cooling fan speed is controlled by a combination of these outputs. Refer to the following table.
If you don't understand these thing's listed above your best bet is to take your vehicle to a qualified repair shop . Have the vehicle checked for DTC'S - diagnostic trouble codes !

Getting a code for smog pump


better check that info again. inspect belt routing diagram and vacuum diagram for thermactor pump and thermactor air system parts being present on your calibration. to my recollection there was no thermactor air used. where would they put all that plumbing?
pump, diverter valve, exhaust check valves, upstream and downstream air tubes? a ford has a label on the radiator support depicting the usage, hose color, and general vicinity in a schematic for ford technicians to identify. there is also a belt routing diagram that depicts the pulleys for the components. you dont have one...right?
you may have a code glossary for older vehicles. get the right manual at the library for free and restart diagnosis. or goto the emissions authorized repair facility and get the question answered after a quick self test

2005 crown victoria sport lx 4.6. Was idling along in traffic and car just died. No stutter or anything just died. Pulled over to the side, turned off the ignition let it sit a minute, started right back...


Electronic's ,go figure .. Not all gliches set code's . Could be any number of thing's - sensor's , modules etc..... A professional Tech would have trouble finding what was wrong , even with profession diagnostic test equipment , scanners etc..... It would be better if it died an wouldn't start back up . Check for TSB'S -
technical service bulletins. Check battery an connection's , loose wire's for sensor's etc... engine . That's about all you could do. Hooking up a professional scan tool an checking engine sensor data inputs to the PCM - engine computer . There maybe a bulletin for a reflash of the PCM .

What does check engine code 18 mean on a 1985 ford crown victoria? 5.0 engine


Code 18 is a spout circuit problem. You probably need the flow chart to check all of the components in that circuit which include the ecm, the temp sensor, and the engine control module among other things.
