Didnt specify vehicle --generic answer --have vehicle scanned for the trouble code -and test your emissions especially the catalytic converter if clogging or failing can cause overheating

How many miles do i need to drive before my buick lesabre reset itself


Unfortunately it is not a certain amount of time or miles that the car needs to be driven.

There are several 'readiness monitors' that basically cover each emissions related system. For instance there is an EVAP monitor that checks the EVAP system and all of it's components under certain specific conditions (No VSS, TPS, O2 sensor, IAT, MAP, Fuel trim, Injector ciruit, EGR pintle position, ECT, or MAF sensor DTC codes set; Start up engine temp 40F-86F; gas tank between 15% and 85% full, Barometer above 75 kPa, system voltage 8V-16V).

So more information is needed as to what failed you the first time. What DTC code was triggered?

If the problem has been fixed right, the history codes will go away after 40 CONSECUTIVE drive cycles WITHOUT the problem re-occurring.

Good Luck.

What is the drive cycle of a 2003 grand am


The drive cycle is a series of conditions that you drive a vehicle to prepare the emissions systems for an emmisions test.

the drive cycle that is most common to GM vehicles is the following;

1. cold start vehicle and allow to warm up to driving temperature, then set a load on the engine, ie. turn on radio and A/C MAX and headlights.
2. reverse vehicle for approx. 15-20 ft.
3. from a stop, drive vehicle at 35mph @ 25% throttle for 15min
4. allow vehicle to slow to a near stop without using hte brake pedal.
5, begin driving vehivle again 45mph @ 50% throttle for 15-20 min.
6. check for emissions status and test.

***OBDII vehicles (95-99) can have up to (2) two emissions monitors at unready status for PA and can sucessfully submit a "pass" status.
vehicles that are 1988 (OBDI) are emissions exempt.

If i remove my aircon compresser will my car still be safe to drive ???


If you remove the A/C compressor and don't make the needed changes for the serpentine belt to still be installed, then no it won't be safe ot drive. You won't have any power steering for one and that would make turning the wheels extremely difficult. Since the water pump also need the sepentine belt to operate, your engine will overheat in a short amount of time.

Code says evaporator purge solenoid


Which code specifically? Do not assume you need a new solenoid. Our recommendation will depend on the specific code and some troubleshooting results. I usually recommend checking over all the EVAP vacuum lines and the gas cap too whenever there is a purge valve code. Check the vacuum lines at the cannister in the left rear bumper. I will paste info on the purge solenoid below.

P0440 Evaporative emission (EVAP) system - malfunction

Possible causes: Hose connection(s), intake leak, EVAP canister purge valve


P0441 Evaporative emission (EVAP) system - incorrect flow detected

Possible causes: Hose connection(s), intake leak, EVAP canister purge valve


P0442 Evaporative emission (EVAP) system - small leak detected

Possible causes: Hose connection(s), intake leak, EVAP canister, EVAP canister purge valve


P0443 Evaporative emission (EVAP) canister purge valve - circuit malfunction

Possible causes: Wiring, EVAP canister purge valve, ECM


P0444 Evaporative emission (EVAP) canister purge valve -open circuit

Possible causes: Wiring open circuit, EVAP canister purge valve, ECM


P0445 Evaporative emission (EVAP) canister purge valve -short circuit

Possible causes: Wiring short circuit, EVAP canister purge valve, ECM


P0450 Evaporative emission (EVAP) pressure sensor - circuit malfunction

Possible causes: Wiring, EVAP pressure sensor, ECM


P0455 Evaporative emission (EVAP) system - large leak detected

Possible causes: Hose connection(s), intake leak, EVAP canister, EVAP canister purge valve


P0456 Evaporative emission system - very small leak detected

Possible causes: Mechanical fault, hose connection(s), EVAP pressure "sensor


P0457 Evaporative emission system - leak detected (fuel cap loose/off)

Possible causes: Mechanical fault, hose connection(s), EVAP pressure sensor


P0458 Evaporative emission system, purge control valve -circuit low

Possible causes: Wiring short to earth, EVAP valve


P0459 Evaporative emission system, purge control valve -circuit high
Possible causes: Wiring short to positive, EVAP valve


Evaporative Emission Purge Solenoid

Description & Operation
The duty cycle EVAP canister purge solenoid (DCP) regulates the rate of vapor flow from the EVAP canister to the intake manifold. The Powertrain Control Module (PCM) operates the solenoid.
During the cold start warm-up period and the hot start time delay, the PCM does not energize the solenoid. When de-energized, no vapors are purged. The PCM de-energizes the solenoid during open loop operation.
The engine enters closed loop operation after it reaches a specified temperature and the time delay ends. During closed loop operation, the PCM cycles (energizes and de-energizes) the solenoid 5 or 10 times per second, depending upon operating conditions. The PCM varies the vapor flow rate by changing solenoid pulse width. Pulse width is the amount of time that the solenoid is energized. The PCM adjusts solenoid pulse width based on engine operating condition.
Removal & Installation
The duty cycle evaporative (EVAP) canister purge solenoid is located in the engine compartment near the brake master cylinder.

  1. Disconnect electrical connector at solenoid.
  2. Disconnect vacuum lines at solenoid.
  3. Lift solenoid slot from mounting bracket for Removal & Installation.

To Install:
  1. Position solenoid slot to mounting bracket.
  2. Connect vacuum lines to solenoid. Be sure vacuum lines are firmly connected and not leaking or damaged. If leaking, a Diagnostic Trouble Code (DTC) may be set with certain emission packages.
  3. Connect electrical connector to solenoid.

Overheating when on highway or using air conditioner


The condenser for the ac is not getting enough air,look for the reason,look in front of the car at the radiator,see if there is something restricting air flow threw the radiator and condenser.

It will die on me while driveing? Sometimes will restart after while still driveing? Also, sometimes will not start till the fourth or fifth try.


Are you topping off the tank (MAX OUT) of while you're filling?

The emission control system can soak with gasoline if you over fill.


Few ounce of fuel can trapped in the EVAP system

Locate the emission line that lead to the charcoal canister and let it air out under direct sunlight.

After 3-5 hours,reconnect the line and use starting fluid to start the car.

After 10 minutes of warm up time,then take it for a short test drive.
