Check the ambient air temp sensor you can read it with a scan tool it may have slipped out of calibration. an the other thing is the crank sensor or ignition module all can be checked with a lab scope and I dont know of any other way
If this information is helpful please give me a good rating and contact me if I can help in this matter Thank you,Randy

Engine Coolant Over Temperature
Number of Trips to Set Code: 1
Trouble Code Conditions:
Engine is running. Engine coolant temperature is higher than 50 C (122 F). Intake Air Temperature (IAT) is higher than 35 C (95 F). Engine soak time is higher than 360 minutes, or start-up coolant temperature is less than 45 C (113 F). Engine Coolant Temperature (ECT) sensor reading is greater than 107 C (224.6 F).
Possible Causes:
  • Sensor
  • Circuit
  • ECM

in pure simple terms
the engine overheated,
try a new thermostat
or check levels in the RAD, cold.
Radiator fan dead?>

Loss of power


Forenza 2004
this is a Suzuki, id sell it, and is not even real Suzuki its a badged
product. actual. Daewoo Lacetti
Daewoo can't sell cars here so suzuki tries and fails... amazing car.

p0217 means overheated.
and when overheated power is lost. stop that or burn up the engine.
do the service on engine, 60,000 miles. steps.
and a new thermostat. i bet yours is 10 years old,,huh and END of life.
non last over that.
id sell it. when fixed, Suzuki's are no good.

FSM data.
Trouble Code Conditions:
Engine is running. Engine coolant temperature is higher than 50 Deg C (122 deg F). Intake Air Temperature (IAT) is higher than 35 deg C (95 deg F). Engine soak time is higher than 360 minutes, or start-up coolant temperature is less than 45 deg C (113 deg F). Engine Coolant Temperature (ECT) sensor reading is greater than 107 deg C (224.6 deg F).
Possible Causes:
  • Sensor ECT
  • Circuit
  • ECM

the fsm skips bad thermostat. odd that... huh"?
and dead cooling fans.
and clogged radiator.
etc.
the first step is to see if it really is overheated, with a IR pyro gun.
if not, the ECT is bad
if is overheated, then fix that, as the ECT didnt lie.

simple , the sensor lied, (nah) or did overheat.

or air pockets at the ECT, low coolant actual.

No hot air


Sounds like the problem lies in the thermostat, When the engine thermostat fails to close fully, the engine coolant temperature may fall. Low engine temperature causes several problems and may cause the heater to blow cool air. Make sure about that.

Where is the temperature gauge hand supposed to


The needle should stay at or just below the 3/4 mark but it may go slightly higher but that would be rare. An example would be driving with the car loaded with 4 people, a/c running on high with outside temperatures of 95 degrees or more.

Ac not working


1st you must check for correct refrigerant levels in ac system, must be done with a/c guages, you have a pressure switch that senses correct pressure in a/c system if you are low in refrigerant the a/c will not come on. if you have good pressures high side 70-95 low side 70-95 depends on ouitside air temperature, with the engine off then look at the switch in the high pressure line, jeep also has a fuse in the fuse box under the hood and a a/c relay please check those too. I hope this helps. (red is high side hose- small fitting plug , blue is low side- larger fitting If ac is working and compressor is on good pressure ranges from high side the red hose 160 to 230 depending on temperature outside; low side blue hose 27-46 low side depending on outside temperature, Wear glasses to protect your eyes. I hope this helps good luck

Air conditioner fan shuts off 95 silverado


It runs of a temperature switch. It only comes on when the condensor needs it to. This is completely normal

No ac


The ambient air temperature sensor is bad or has a connection/wiring problem. It is not blowing cold air because it thinks the outside air is less then 35degrees. When the computer sees outside air less than 35 it disables AC so that ice will not form inside the vehicle and in HVAC system. The sensor is directly behind the front grill. You might be able to check it for connection/corrosion/frayed or damaged wires. If no evidence of this I would replace it.
