I need help finding the coolant temp sensor can u please help me


NOTE Use care when handling the ECT sensor. Damage to the coolant sensor will affect the operation of the fuel control system.

NOTE The engine coolant temperature sensor is located on the intake manifold water jacket or near the thermostat housing. On the 4.6L engine, the coolant temperature sensor is located on the rear cylinder head, at the cruise control servo bracket. It is necessary to drain coolant from the cooling system to a level below the sensor, prior to sensor removal.
  1. Disconnect the negative battery cable.
  2. Drain the coolant level below the height of the ECT and recycle the engine coolant.
  3. Detach the electrical connector at the sensor.
  4. Remove any obstruction to access the ECT.
    1. On the Catera, this would include removing the intake plenum and the intake bridge.

  5. Using a deep well socket, remove the sensor.

To install:
  1. Coat the threads of the new sensor and install it in the engine. Tighten to 15 ft. lbs.
  2. Install the electrical connector.
  3. Refill the system with coolant.
  4. Connect the negative battery cable.

Promblems P0340 P2105 P2106 P2110 P161B???? vehilce has limited power and slows down while driveing due to limited power vehicle has not ever shut off i believe it s the actuator on the throttle...


Diagnostic Test Code (DTC) P0340 is a Camshaft Position Sensor (CMP) fault. This can be caused by several things including faulty CMP sensor wiring, a defective CMP sensor, a shorted Voltage Reference (VREF) circuit or interference from high voltage ignition system problems.

The Camshaft Position (CMP) sensor is used to correlate crankshaft to camshaft position so that the Engine Control Module (ECM) can determine which cylinder is ready to be fueled by the injector. The CMP is also used to determine which cylinder is misfiring when a misfire is present.

Conditions for Setting the DTC

> CMP sensor pulse is not detected at the correct interval every 4 cylinders.
> Engine is running.


DTC P2105: Throttle Actuator Control (TAC) System - Forced Engine Shutdown
Conditions for Setting the DTC

> Ignition ON.
> The ECM detects the system is in Forced Engine Shutdown Mode.

DTC P2106: Throttle Actuator Control (TAC) System Performance - Throttle Limitation Active
Conditions for Setting the DTC

> Ignition ON.
> The ECM detects the system is in Limit Performance Mode

DTC P2110: Throttle Actuator Control (TAC) System - Forced Limited Engine Speed
Conditions for Setting the DTC

> Ignition ON.
> The ECM detects the system is in Power Management Mode.

PLEASE NOTE that these codes DO NOT NECESSARILY mean that you have a defective TAC. They DO NOT NECESSARILY mean that your TAC is malfunctioning. (although they COULD mean these things) These codes are mostly for informational purposes to let you know that the throttle system is being overridden by the engine control computer. The REASON that this override has taken place must be DIAGNOSED.

DTC P161B: Control Module Torque Performance:
The actual explaination for this one is pretty long and drawn-out. But to put things in simple terms, the trouble shooting charts pretty much say to inspect the engine for hardware problems that could allow excessive air flow. If there are no such problems found, replace the ECM.

WITH ALL OF THAT BEING SAID:

There is a Technical Service Bulletin (TSB) that addresses ALL of the codes listed above and involves replacement of the Manifold Absolute Pressure (MAP) sensor to fix the vehicle.

Here is a brief description of the bulletin:

FORENZA
Section Title: Engine
TSB No. TS 18 02228

Division: Automotive
Category: Technical

SUBJECT:
ENGINE HAS NO POWER, HESITATES, STUMBLES ON ACCELERATION, CHECK ENGINE LIGHT IS ON WITH MULTIPLE DTCS WITH P161B (CONTROL MODULE TORQUE PERFORMANCE) AS THE PRIMARY DTC

See table below for possible accompanying DTCs.

I have a 2000 Jimmy. It appears to have black gunk in the engine coolant area (oil?). I am not sure what to do. Advise please.


Is your oil level low? Do you have an oil cooler going to the radiator? If there is then its possble the cooler is leaking inside the radiator.

Does the cooling system still use Dex-Cool? The S trucks are one of the models that seem to have problems with the Dex-Cool. People would usually see a dark brown mud basically in their cooling system.
If it still uses Dex-Cool then I would sugest draining and flushing the cooling system (including a good flushing of the heater core. Remove the hoses and force water through with a garden hose) and refilling with another coolant/antifreeze.

Will a canister purge vaule throw a oxgen sensor code


No, Each item has its own code more or less. A bad purge valve may give you a warning that the Evap system has a problem and this would include lines, tank, and the fuelcap. Sometimes the Code would be more specific naming the canister purge valve separately without including the lines, tank, or the fuelcap.

But the purge valve and the O2 sensors are completely different systems. The O2 sensors go on the exhaust and the purge valve is grouped with the fueltank. The comparision of the difference is like the purge valve belongs with the fueltank group and the O2 sensors belong with engine controls after the fuel system has finished its job.

I hope my solution is very helpful in explaining how each system is separate.

Changing water pump 2000 ford focus


Changing a water pump is pretty basic. Since the coolant system is a closed system you only need to be concerned with that system. For instance you since you have to mess around with it anyway you might as well change the thermostat and flush the coolant system. Make sure your radiator hoses are in good shape and that's about it.
If you have basic mechanical skills and tools you will have no problem replacing a water pump.


As far as information with the actual replacement there are a number of experts here including myself that could explain how to do it.
However no matter how good our explanations are it just can't compare to a good repair manual.
A repair manual for your car at Auto Zone would likely cost between $12 and $15. It is a great investment if you are going to keep your car for any length of time. When you sell, it shows the buyer you took the time to maintain and repair it right.
I personally like Haynes Manuals.
I hope this helps.

SECTION 303-03: Engine Cooling 2001 Lincoln LS Workshop Manual
DESCRIPTION AND OPERATION Engine Cooling The cooling system components include the:
  • block heater (optional)
  • cylinder head temperature sensor
  • fan blade, fan motor and fan shroud assembly
  • radiator
  • pressure relief cap
  • degas bottle
  • radiator draincock
  • water pump
  • oil cooler (optional)
  • water thermostat
The water thermostat:
  • controls the engine coolant temperature.
  • allows quicker engine warm-up.
The degas bottle:
  • provides a location for system fill.
  • contains coolant expansion and system pressurization.
  • provides air separation during operation.
  • replenishes the engine coolant to the system.
The fan blade draws air through the radiator to help cool the engine coolant.
The fan motor:
  • operates only when the engine is running.
  • will not operate when the engine is off.
The engine coolant flows:
  • from the lower radiator hose to the water pump.
  • from the water pump to the engine block and the cylinder heads.
A closed water thermostat returns the engine coolant to the water pump. An open water thermostat allows the engine coolant to flow to the radiator.
Unsatisfactory coolant materials:
  • Alcohol-type antifreeze does not provide adequate water pump lubrication.
    • has lower boiling point
    • reduced antifreeze protection
  • Alkaline brine solutions will cause serious engine cooling system damage.
The cylinder head temperature sensor provides a signal to the temperature gauge.
  • will invoke failsafe cooling.
The optional block heater:
  • electrical heating element is installed in the block cooling jacket.
    • uses a standard 110V (220V in Europe) electrical supply
  • keeps the engine coolant warm during cold weather.
The auxiliary water pump (3.9L only):
  • provides heater coolant flow boost.
  • has a secondary function of providing engine-off cooling.

Code P0158


Bank 2 sensor 2 is the post-catalytic converter O2 sensor on (usually) the driver's side. It's the sensor that the car uses to monitor the efficiency of the catalytic converter. Whichever side of the engine has cylinders 4, 5, and 6 is bank 2 (you'll probably find that information on a decal underhood). Flashing the computer could be as easy as what you're doing (resetting by disconnecting the battery), or it may involve a more detailed process including diagnostic software. It's most likely though that what you are doing is all that's required - disconnecting the battery for 30 minutes or so puts the ECU back into learn mode, and it basically starts fresh to relearn the engine's operating parameters.

Fifteen minutes! you have bigger problems than only the fans the fans are controlled by a thermo switch that is heated by the coolant, If you have no coolant the sensor cannot activate But fifteen minutes seems like you may have a headgasket problem and steam cannot heat the coolant sensor.OperationNotesThe electric cooling fan operates when the engine cooling temperature exceeds a certain value. The cooling fan on this engine is controlled by the Powertrain Control Module (PCM) . The PCM turns the cooling fan ON by grounding the coil of the cooling fan relays when certain conditions are met. When the A/C is requested, the cooling fan will also be turned ON.

Power for the cooling fan motors are supplied through Maxifuses(R). The cooling fan relays are energized when current flows from the fuses in the Underhood Accessory Wiring Junction Block, and through the relay coils to ground through the PCM. The Coolant Fan 1 Relay Control Circuit is grounded for low speed fans operation. During low speed fans operation, both fans run at a slow speed. The Coolant Fan 1 Relay Control Circuit is grounded for high speed operation. During high speed fans operation, both fans run at high speed.

IMPORTANT: When certain Diagnostic Trouble Codes (DTCs) are present, the PCM may command the cooling fans to run all the time. Perform the A Powertrain On Board Diagnostic (OBD) System Check prior to diagnosing the engine cooling fans.

For more information regarding the Charging System, refer to Charging System Description , and Charging System Circuit Description in Starting and Charging.

If a problem that involves the low speed cooling fan relay control circuit exists, DTC P0480 Cooling Fan Relay 1 Control Circuit should set. If the problem affects the high speed cooling fan relay control circuit, DTC P0481 Cooling Fan Relay 2 Control Circuit should set. A problem with the ECT sensor should set DTC P0117 Engine Coolant Temperature (ECT) Sensor Circuit Low Voltage, DTC P0118 Engine Coolant Temperature (ECT) Sensor Circuit High Voltage, DTC P1114 Engine Coolant Temperature (ECT) Sensor Circuit Intermittent Low Voltage, DTC P1115 Engine Coolant Temperature (ECT) Sensor Circuit Intermittent High Voltage. Any of these DTCs will affect cooling fan operation and should be diagnosed before using the Electric Cooling Fan Diagnosis.

For more information regarding the Cooling System refer to Engine Cooling Fan Description - Electric, and Cooling System Description in Cooling System.
