DTC P0128 Engine Coolant Temperature (ECT) Below Thermostat Regulating Temperature
Circuit Description
The engine control module (ECM) monitors the temperature of the engine coolant for engine control and as an enabling criteria for some diagnostics. The amount of air flow into an engine is proportional to the amount of heat an engine generates. The ECM monitors the amount of air flow into the engine to calculate engine coolant temperature (ECT). The ECM uses the calculated temperature to determine if the engine has warmed up to the thermostat regulating temperature. If the coolant temperature does not increase normally or does not reach regulating temperature of the thermostat, diagnostics that use the ECT as enabling criteria, may not run when expected. If the engine coolant temperature fails to reach the thermostat regulating temperature, before a predetermined amount of air flow enters the engine, this DTC sets.

DTC P0441 Evaporative Emissions (EVAP) System Continuous Purge Flow
System Description
This DTC tests for continuous intake manifold vacuum flow to the Evaporative Emission (EVAP) System. The control module seals the EVAP system by commanding the EVAP canister purge solenoid valve Closed and the EVAP canister vent solenoid valve Closed. The control module monitors the fuel tank pressure (FTP) sensor to determine if a vacuum is being drawn on the EVAP system. If vacuum in the EVAP system is more than a predetermined value within a predetermined time, this DTC sets.

DTC P0700 Transmission Control Module (TCM) Requested MIL Illumination
This diagnostic trouble code (DTC) indicates that an emission related transmission DTC set in the transmission control module (TCM). The engine control module (ECM) receives the TCM DTC information over the serial data circuit. The ECM turns ON the malfunction indicator lamp (MIL) when the TCM sends a message over the serial data circuit requesting MIL illumination. The ECM will also store the freeze frame/failure records data for a transmission DTC. The DTC information for the ECM will only display DTC P0700, but the freeze frame/failure records data will display the transmission DTC that set.
DTC P1781
Conditions for Setting the DTC
• Transmission control module (TCM) detects that malfunction of engine speed signal for 2 seconds
• No DTC U2105
• Engine Misfire Detected

Does the speedometer work ?

clouds of smoke out the rear exhaus ,What color ? blue smoke is oil , white smoke is most of the time coolant is getting into the engines cylinders , Black the engine is running rich ,too much fuel . DTC P0135 HO2S Heater Performance Bank 1 Sensor 1
DTC P0147 HO2S Heater Performance Bank 1 Sensor 3
DTC P0340 IC Module Cam Reference CKT No Frequency
DTC P0401 Exhaust Gas Recirculation (EGR) Flow Insufficient
P0441 has nothing to do with the gas cap !
DTC P0441 Evaporative Emission (EVAP) System No Flow During Purge
DTC P1441 Evaporative Emission (EVAP) System Flow During Non-Purge

P0441 & P1441 will be back , may take a day or two , but will be back because gas cap has nothing to do with it .

Honestly , you should take your vehicle to a qualified repair shop !

get new gas cap it will give a p0441 code!!!

DTC P0441 - Evap. Emission System Incorrect Purge Flow

Possible causes: poor/loose connection, faulty purge control solenoid valve(pcvs), faulty PCM.

Check for loose electrical connector and for loose or broke vacuum hose to it. If ok, you will need a voltmeter and vacuum gauge to test it. If fails test, replace it, if ok, then likely a faulty pcm. Most of the time it is either a bad vacuum hose to it or faulty pcsv.

With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

Common Chrysler fix - Replace Leak Detection Pump / LDP

Repair damaged EVAP lines or canister

Repair open or short in voltage feed circuit to Purge Solenoid

Repair open in PCM purge command circuit

Replace purge Solenoid

Replace vacuum switch

Repair restriction in Evap line or canister or solenoid

Repair resistance in purge connector

Replace PCM

hope helps.

Diagnostic Test Code DTC P0144 is not a valid code for your Montero. It is also not a purge solenoid code even if it was a valid code.

Do you mean DTC P0441?
The computer commands the purge solenoid to open and apply vacuum on the evaporative emissions system and moitors the fuel tank pressure (FTP) sensor to see if vacuum is being applied. It also commands the purge solenoid to close and closes the vent solenoid and monitors the FTP data to see if vacuum is being applied when it is not supposed to.
DTC P0441 sets when either the vacuum does not apply when it is commanded to or there is vacuum being applied when is is commanded not to.

Possible causes are mechanically sticking or leaking purge solenoid, clogged, collapsed, or disconnected purge vapor lines. This is not likely to be caused by the purge solenoid electrical circuits since this is not a circuit code.

Two choice dudes code there...

DTC P0441 - Evaporative Emission (EVAP) Control System Incorrect Purge Flow
EVAP emission canister purge is contolled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.

DTC P1441 - Evaporative Emission (EVAP) System Flow During Non-Purge.
Most generally caused by a purge valve stuck open. the only way to diag for sure is with a gm tech 2 scan tool and a smoke machine. but if dont mind spending a few bucks as a good quess. Replace the purge valve.


Hope this helps.

Here is detailed info:

These codes tell you that there is a vaccuum leak.

Check your gas cap to see if it is tight, if it is, you should probably replace it as that will cause the codes to appear. Here is some more detailed information as well.

DTC P0440 is recorded by the ECM when evaporative emissions leak from the components within the dotted line in Fig. 1, or when the vapor pressure sensor malfunctions.

DTCs P0441 and P0446 are recorded by the ECM when evaporative emissions leak from the components within the dotted line in Fig. 1, or when there is a malfunction in either the VSV for EVAP, the VSV for pressure switching valve, or in the vapor pressure sensor itself.

Basically, the P0440 code is set when there is a vacuum leak in the system, at cold engine start the VSV is open and pulls the lines into a vacuum. Then the VSV closes and the vacuum should stay roughly at the same spot. If the pressure increases rapidly (aka loses vacuum) then the pressure sensor sees that and sets a DTC and turns on the MIL. From what I gather from P0441, the system doesn't pull into a vacuum.

DTC P0441 - Evaporative Emission Control System Incorrect Purge Flow

What does that mean?
This indicates that a part of the EVAP control system is no longer fuctioning correctly. The EVAP system consists of many parts, including (but not limited to) the gas cap, fuel lines, carbon canister, purge valve, and other hoses. The (EVAP) emission control system prevents the escape of fuel vapors from a vehicle's fuel system. Fuel vapors are routed by hoses to a charcoal canister for storage. Later, when the engine is running a purge control valve opens allowing intake vacuum to siphon the fuel vapors into the engine.

EVAP emission canister purge is contolled by a valve which allows engine vacuum to pull stored fuel vapors from fuel tank into the engine to be burned, rather than be vented to atmosphere. A vacuum switch is used to detect when flow exists. If the PCM commands purge and sees that the switch is closed (indicating no detected purge flow) P0441 is set.

Symptoms
Likely, no symptoms will be discernible to the driver, other than the illuminated Check Engine Light.

Causes
A code P0441 could mean one or more of the following has happened:
* Bad vacuum switch
* Broken or damaged EVAP line or canister
* Open in PCM purge command circuit
* Open or short in Voltage feed circuit to Purge Solenoid
* Faulty purge solenoid
* Restriction in EVAP solenoid, line or canister
* Corrosion or resistance in purge connector
* Bad PCM

Possible Solutions
With a P0441 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

* Common Chrysler fix - Replace Leak Detection Pump / LDP
* Repair damaged EVAP lines or canister
* Repair open or short in voltage feed circuit to Purge Solenoid
* Repair open in PCM purge command circuit
* Replace purge Solenoid
* Replace vacuum switch
* Repair restriction in Evap line or canister or soleniod
* Repair resistance in purge connector
* Replace PCM

Other EVAP DTCs: P0440 - P0441 - P0442 - P0443 - P0446 - P0453 - P0455 - P0456

smoke test for leaks.

reset light and make sure gas cap is secure.
