SOURCE: emissions test code comes up as 0743 torque

U have a problem in the transmission torque converter clutch control circuit, most likely the solenoid switch that applies the lock up clutch of the torque converter is defective or a the torque converter itself is defective, the trans pan will need to be removed to check the problem further.

while it is possible to perform that swap, the newer 2000+ transmissions will have updated internals and such.

so will it work............. yes.

is it optimal.................no.

SOURCE: illustrated diagram on how to remove speed sensor for windstar 98

The Vehicle Speed Sensor is located on transaxle, at the rear of the engine. I would check the harness connector to be sure it is clean and connected tightly. Also check the wiring for cuts and chaffing. Since it is fairly inexpensive, only about $42.00 from Ford, you may want to consider replacing it, at least to eliminate it as a possibility. You may want to go to a muffler shop to have this done like speedy, I believe the flex pipe needs to be undone to get to the VVS. If there is an Auto Zone around your area, you could always ask them for the step by step instructions to replacing the VVS, and it's free of charge. Good luck and hope this helps.

SOURCE: o2 sensors on 1998 ford windstar

1998 Ford Truck Windstar 3.8L SFI 6cyl, there are 4 oxygen sensors on the Windstars They are divided into 2 banks of 2. Bank 1 is the for the rear 3 cylinders of the engine - Bank 2 is for the front 3 cylinders. Bank 1 / Sensor 1 (upstream) is located just below, in the pipe, the exhaust manifold on the back of the engine.

REMOVE TIP: you may have to bend part of the transmission heat shield out of the way - be sure to put it back when done.
Bank 1 Sensor 2 (downstream) is located just past the drivers side catalytic converter.
Bank 2 Sensor 1 (upstream) is located just below the exhaust manifold, in the pipe, at the front of the van - access is from the top.
Bank 2 Sensor 2 (downstream) sensor is located just past the passenger side catalytic converter.

NOTES: * Use lots of penetrating oil - allow to soak - to make removal easier and avoid damaging the exhaust pipe

Hope this help; TY for using Fixya (remember rated and comment this).

Can either of these codes cause my 1999 Oldsmobile bravada SUV to over heat: P0442 ornP1361 or P0117??


code p 0442 refers to EVAP system so that is unlikely
check the fan operation and if you have a viscous fan hub ( fan clutch ) replace it
if you have electric fans , check coolant temperature sensor for operation , fuses , relay and fans
overheating is from low coolant levels , head gaskets/cracked heads, blocked radiator cores , fins flaking off core tubes, incorrect timing, blocked exhaust( cat converter)problem thermostat, over loading /over speeding, overdrive not engaging
if you over heating is predominately at lights , slow moving traffic or high engine rpms with low speed --check the fan operation and if it is viscous fan hub driven --replace the hub or if electric fans have that circuit checked out

it also refers to engine coolant temperature (ECT) sensor --- circuit malfunction=== causes --- wiring-- ECT sensor
bump the cat converter with the heel of your hand and if it rattles replace the cat converter
if the cat converter is solid , replace the ECT

Which one is the ect sensor on my 2002 ford ranger, 4.0 v6 4x4, and how do I replace it


P0117 - Engine Coolant Temperature (ECT) Circuit Low Input Indicates the sensor signal is less than Self-Test minimum. The ECT sensor minimum is 0.2 volts or 121°C (250°F). Note on some vehicles that are not equipped with an ECT sensor, CHT can be used and can set this DTC.
  • Grounded circuit in harness
  • Damaged sensor
  • Improper harness connection
  • Damaged PCM
ECT V PID reading less than 0.2 volts with key ON and engine OFF or during any engine operating mode indicates a hard fault.

What can cause trouble code p0118 engine coolant temp sensor ( high voltage input ) 99 intrepid 2.7 v6


The engine coolant temperature (ECT) sensor is a variable resistor, that measures the temperature of the engine coolant. The ECT sensor has a signal circuit and a low reference circuit. The engine control module (ECM) supplies 5 volts to the ECT signal circuit and a ground for the ECT low reference circuit. When the ECT is cold, the sensor resistance is high. When the ECT increases, the sensor resistance decreases. With high sensor resistance, the ECM detects a high voltage on the ECT signal circuit. With lower sensor resistance, the ECM detects a lower voltage on the ECT signal circuit. If the ECM detects an excessively high ECT signal voltage, which is a low temperature indication, DTC P0118 sets. You have A bad coolant temp sensor or a wiring problem !

Jetta 1996 p0117 code


Hi there:
DTC P0117 - Engine Coolant Temperature (ECT) Circuit Low Input
The ECT (Engine coolant temperature) sensor is a thermistor located in the engine block or other coolant passage. It changes resistance with changes in temperature of the coolant that it's in contact with. It's usually a two wire sensor. One wire is a 5 volt reference from PCM (Powertrain Control Module) and the other is a ground supplied from PCM.

As the temperature of the coolant changes, the resistance of the sensor changes. When the engine is cold, the resistance is high. When the engine is warm, the resistance is low. If the PCM detects a signal voltage lower than the normal operating range of the sensor then P0117 code will set.

Potential symptoms include:
MIL (Malfunction Indicator Lamp) illumination
Poor fuel economy
Poor drivability
Engine may run rough or blow black smoke out the tailpipe
May not idle
May start and then die

Potential causes of the P0117 code include:
Bad ECT sensor
Short to ground on ECT signal circuit
Faulty or damaged connectors
Wiring harness damaged
Loose terminals at ECT or PCM
POSSIBLY an overheated engine
Bad PCM

Possible Solutions:
Since this code is for an abnormally low signal to the PCM from the ECT, the PCM saw a excessively "hot" condition in the engine coolant. This could be due to faulty ECT sensor or wiring, but it could, conceivably, be caused by an overheated engine.So if your engine was overheated diagnose that first. Having said that here are the possible solutions:

Using a scan tool, with KOEO (Key on engine off) check the ECT reading on the display. On a cold engine the ECT reading should match the IAT (Intake Air Temperature) sensor reading. If it doesn't, replace the ECT sensor.

1. If the ECT reading is showing an excessively hot reading, for example more than 260 deg. F, then unplug the ECT sensor. This should cause the ECT reading to drop to the extreme cold reading (around -30 deg.F or so). If it does, replace the sensor, because it's internally shorted. If it doesn't change the reading, the check for a short to ground on the signal circuit of the ECT wiring. It could be that the two ECT wires are shorted to each other. Look for any chafing or melted wiring. Repair as necessary.

a. If you can't find any wiring problems and the ECT reading doesn't drop to the extreme coldest when unplugged, then, check for voltage coming out of the PCM on the signal wire's pin at the PCM connector. If there isn't any voltage, or it is low, then the PCM may be bad. NOTE: On some models it is possible for the 5 Volt reference signal to be temperarily shorted. This can happen if an engine sensor internally shorts the 5 Volt reference. Since the 5 Volt reference is a "shared" circuit on many models, this will cause it to be abnormally low. Usually, though this will be accompanied by several other sensor codes. If you suspect that may be the case, unplug each sensor until the 5 Volt reference reappears. The last sensor unplugged is the offending sensor. Replace and recheck the signal wire from the PCM connector

2. If the scan tool ECT reading seems normal at this time then the problem may be intermittent. Use a "wiggle" test to manipulate the wiring harness and connectors while watching the ECT reading on the scan tool. Repair any wiring or connectors that are loose or corroded. You could check the Freeze frame data if your scan tool has that function. It will show the ECT reading when the failure occurred. If it shows the reading to be at the hottest extreme then replace the ECT sensor and see if the code reappears.

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.

Ect high input


Hi: The engine coolant temp sensor, or ECT is located close to where the upper radiator hose conncects to the engine. It is a hex shaped sensor, with a electrical connector coming straight out from the end.
