Engine managment light on code reader says heater control sensor fault where is this on fiesta 2003 petrol
If its a diesel engine then their is a relay/timer box but this is a petrol so iam at a loss as to weither this is a code reader fault reading the fault as i have two code readers and cannot get into a ford of this age it will only read the vin number so iam at a loss as to either a cab heater fault which i cannot see throwing the engine light on or the autochoke sensor because all these code readers give the answer in good old american and we all know they cannot spell colour correctly or pronounce aluminium.Bless them no go for the engine autochoke sensor and check that out first but the main cause of the light on with a ford of this year is the O2 sensor their are two wires the same colour out of the four wires now disconnect the socket and check for a continuety on the sensor side of the socket and if no continuety then renew the sensor if a check shows continuety the check the opposing plug socket and check for a 12v supply .Hope this helps and sorry i cannot pronounce aluminium or know the difference between a saturn or a windstar and think all nissans are diesel ,red face on my part here but iam a brit living in spain .

You need to check for codes to begin with. If no codes then we can start guessing. A code is pretty strait forward. Without a code, hands on will be the only way to diagnose this issue.

ok you have two banks of cylinders, the bank one cylinder bank is the one near the firewall or rear bank, the sensor you want is in the exhaust pipe from that rear bank it is before the catalytic converter.

The battery could be slightly weak, making the computer go on the fritz,
try a fresh battery!!!!
The rev counters bounce often with a weak battery.
Leave feedback good or bad.

When the service engine soon light (Also called the check engine light) is turned on this is to alert you to the fact that powertrain control module (computer) has detected a failure somewhere in the systems it controls, this can be the transmission or the engine or emission system, there are fault codes set in the modules memory for these faults. What needs to happen now is to have the powertrain control module scanned with a special tool called an OBD2 electronic engine control scanner or a OBD2 code reader. Once the code(s) are read then you must perform the diagnostics for each code and make the appropriate repairs based on the findings of the diagnosis that was performed, this is called doing "Pinpoint" testing.
