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

Can't go through inspection like that. Strip it back and replace what ever you have to,to do the job correctly.

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.

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

Engine light cam on, used code scanner, got code #44, thermactor air control system, what do i need to do?


A code 44 on a 1999 caviler ? for 1999 the code should be like a po**** type of code, unless the is the wrong year. a code 44 for an older caviler is the code for a lean exhaust this would be like a 1995 and older, check the engine for any vacuum leaks, listen for any hissing noise you may have a broken or disconnected vacuum hose, if no leaks are found then replace the oxygen sensor, this should take care of the problem is no vacuum leaks are found.

Airbag flashes 10 times misses a flash then repeats


Try clearing the codes & see if it returns. I do not see a code fault 10. Starts at 12.

---------------------------------------------------------------------
Section 01-20B: Restraints, Passive — Supplemental Air Bag System 1995 Town Car, Crown Victoria, Grand Marquis Workshop Manual DIAGNOSIS AND TESTING Diagnostic Trouble Code Clearing Procedure to Clear Diagnostic Trouble Codes from Diagnostic Monitor Non-Volatile Random Access Memory.
Normal Operation
The air bag diagnostic monitor (14B056) continually checks the air bag system for readiness. When a fault condition is detected, the DTC associated with that fault is stored in the air bag diagnostic monitor's Non-Volatile Random Access Memory (NVRAM). After writing the DTC to NVRAM, the air bag diagnostic monitor signals the fault by flashing the appropriate diagnostic trouble code on the air bag indicator. The diagnostic trouble code written to NVRAM is permanently stored in the air bag diagnostic monitor until cleared by the diagnostic trouble code clearing procedure.
  • Upon each cycle of the ignition switch (11572) , the air bag diagnostic monitor checks for diagnostic trouble codes written in NVRAM. If any diagnostic trouble codes exist in NVRAM, the air bag diagnostic monitor will then check to see if these fault conditions are still present.
  • If the conditions of the diagnostic trouble code in NVRAM are still present, then the air bag diagnostic monitor will use the air bag indicator to flash out the diagnostic trouble code number that was written in memory.
  • If the conditions of the diagnostic trouble code are not still present (indicating an intermittent or serviced fault), the air bag diagnostic monitor will use the air bag indicator to flash out a DTC which is the sum of the diagnostic trouble code in NVRAM plus 40.
Example: Due to corrosion, high resistance develops on the driver side air bag circuit. The air bag diagnostic monitor stores a diagnostic trouble code 32 in NVRAM. Upon each cycle of the ignition switch , the air bag diagnostic monitor checks the resistance of the driver air bag circuit.
  • If the resistance is still high, the air bag diagnostic monitor causes the air bag indicator to flash out a DTC 32.
  • If the resistance falls within the normal range due to service or an intermittent condition, the air bag diagnostic monitor causes DTC 72 to be flashed on the air bag indicator.
Once a fault has been serviced, the associated diagnostic trouble code may be cleared from NVRAM. Only diagnostic trouble codes that the air bag diagnostic monitor sees as repaired or intermittent may be cleared (diagnostic trouble codes 52 and above). In no circumstances can hard fault conditions (diagnostic trouble codes 45 and below) be cleared.
  1. Follow the diagnostic procedures as outlined to service the fault condition flashing on the air bag indicator.
  1. Cycle the ignition switch to OFF and then to RUN.
  1. Observe air bag indicator prove-out (six ± two seconds) followed by diagnostic trouble code (52-85) flashing completely one time.
  1. Locate the Diagnostic "Trouble Code Clear" Connector located underneath the glove compartment (06010) containing Circuits 631 (T/R) and 57 (BK).
  1. Use a jumper wire to short Circuit 631 (T/R) to Circuit 57 (BK) or to another good ground. This short must be made after the diagnostic trouble code flashes completely one time, but before the warning light stays on continuously.
  1. Hold short until air bag diagnostic monitor tone sounds (approximately five seconds).
  1. Release short on Circuit 631 (TAN/RED STRIPE) to Circuit 57 (BLACK). This short must be released within 25 seconds after the diagnostic monitor tone sounds. Diagnostic trouble code is now cleared from NVRAM. Next highest priority diagnostic trouble code stored in NVRAM (if one exists) will begin flashing.
