What engine?

Most likely the purge solenoid is leaking. It is usually located on the drivers side of the engine. It will have two plastic/rubber lines going to it and one two wire connector (sometimes the connector is red). Unplug the connector, remove the line that goes to the charcoal canister (the other line goes to the intake), start the engine and see if you can feel vacuum on the port on the Purge solenoid. If you can replace it.

SOURCE: DTC Code of a 1404 , and also a IAT High input malfunction

sounds like the IAT is disconnected, it is either in the flex hose from the air cleaner to the engine or in the air filter housing, on my GM product car it is in the air intake hose, it is small and has a 2 wire connector to it, just pushes and pulls in and out of the flexible air intake hose.

Probably just a dirty sensor or broken wire, but you should proably have your brakes checked to be safe.

SOURCE: where is the iat sensor located on a 1999 chevy cavalier 4cyl

The Intake Air Temperature (IAT) sensor determines the air temperature inside the intake manifold. Resistance changes in response to the ambient air temperature. The sensor has a negative temperature coefficient. As the temperature of the sensor rises the resistance across the sensor decreases. This provides a signal to the PCM indicating the temperature of the incoming air charge. This sensor helps the PCM to determine spark timing and air/fuel ratio. Information from this sensor is added to the pressure sensor information to calculate the air mass being sent to the cylinders. The IAT is a two wire sensor, a 5-volt reference signal is sent to the sensor and the signal return is based upon the change in the measured resistance due to temperature.

Hope helped.

P1441


If you go to this site it lists the definition of this code by make, it also lists the possible causes of the problems that trigger the P1441 to be set in memory. Since you gave no specific info on the car or truck that is the best i can provide to help you diagnose this.

P1442 usually gas cap. P1449 usually vent solenoid. P1441 usually always a faulty FTP sensor. Very problematic to Malibu, Grand Am Cavaliers and Aleros. That would be my first area to check. They are also known for poor wiring connections at the Left rear passthru connector to the fuel tank and vent solenoid, but not necessarily for that code.

1995 chevy cavalier passlock reset


Here is how to do the relearn. Turn ON the ignition, with the engine OFF. Attempt to start the engine, then release the key to ON, vehicle will not start. Observe the SECURITY telltale, after approximately 10 minutes the telltale will turn OFF. Turn OFF the ignition, and wait 5 seconds. Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes, the vehicle is nowready to relearn the PasslockTM Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK.
Important: The vehicle learns the PasslockTM Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle. Start the engine. The vehicle has now learned the PasslockTM Sensor Data Code and/or password.
Thank you for using Fixya and just take you time and follow the instructions above. Good luck

Hope this helps,

Trouble Code: P1441 (2.2L L4 VIN F Auto)
EVAP System Flow During Non-Purge Print this code dataprint_icon_codes.gif
Number of Trips to Set Code: 2
OBD II Monitor Type: CCM Details
Indicators: MIL Details
Trouble Code Conditions:
DTC P0107, P0108, P0112, P0113, P0117, P0118, P0121-P0123, P0125, P0440, P0442, P0443, P0446, P0449, P0452, P0453, P1106, P1107, P1111, P1112, P1114, P1115, P1121 and P1122 not set, engine started, vehicle speed less than 75 mph, system voltage over 10.0v, ECT and IAT sensors from 39-86ºF and within 16ºF at startup, BARO sensor over 75 kPa, fuel level from 15-85%, PCM detected a continuous open purge flow condition with the fuel tank pressure decreasing to less than -11" H2O during the test. The PCM seals the EVAP system by commanding the EVAP Purge valve "off" and the EVAP Canister Vent valve "on". The PCM monitors the fuel tank pressure (FTP) sensor to detect if a vacuum is being drawn on the EVAP system. If vacuum in the EVAP system is more than a set value for a certain time, this code is set.

Possible Causes:
  • An improperly installed or damaged EVAP canister purge valve
  • A temporary blockage in the EVAP canister purge valve, purge pipe, or EVAP canister could cause an intermittent condition
  • FTP sensor is out-of-calibration, damaged or "skewed"
  • Purge solenoid valve is damaged or has failed
  • PCM has failed
  • TSB 02-06-04-046 contains a repair procedure for this code

I have engine light on and I got the check engine light codes: P0121 and P0171 for my 1997 Chevy Cavalier. What does it mean? Thank you!!


A code P0121 may mean that one or more of the following has happened:
  • TPS has intermittent open or short internally
  • Harness is rubbing and causing an open or short in the wiring
  • Bad connection at the TPS
  • Bad PCM (less likely)
  • Water or corrosion in connector or sensor
(TPS = throttle position sensor - mounted on side of throttle body and connected to accelerator linkage.)
Causes A code P0171 may mean that one or more of the following has happened:
  • The MAF (Mass Air Flow) Sensor is dirty or faulty. Note: The use of "oiled" air filters may cause the MAF to become dirty if the filter is over-oiled. There is also an issue with some vehicles where the MAF sensors leak the silicone potting material used to protect the circuitry.
  • There could be a vacuum leak downstream of the MAF sensor.
Possible Solutions Possible solutions include:
  • In the vast majority of cases, simply cleaning the MAF sensor does the trick. Consult your service manual for it's location if you need help. I find it's best to take it off and spray it with electronics cleaner or brake cleaner. Make sure you are careful not to damage the MAF sensor, and make sure it's dry before reinstalling
  • Inspect all vacuum and PCV hoses, replace if necessary
  • Check for a dirty fuel filter and proper fuel pressure
Hope this helps.
