This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. What the P code means is that the powertrain control module PCM has detected something unusual within the torque converter clutch circuit.
The powertrain control module can vary the application of the torque converter clutch for optimal vehicle performance.
P0740 - Torque Converter Clutch Malfunction
If the torque converter clutch application is abnormal usually multiple times the powertrain control module will trigger a Check Engine Light. A mechanic may begin the diagnosis of the P code by first checking the transmission fluid for proper level and condition.
If anything is out of the ordinary, this could be part of the problem. If nothing is wrong with the transmission fluid, the mechanic would then use service information to look up a diagnostic procedure for this code given by the manufacturer and then follow the instructions given.
Keep in mind that this diagnostic may require the transmission to be removed or even disassembled. An easy mistake that could be made is assuming that the torque converter is damaged just because this part is listed in the trouble code.
This may result in a lot of money being spent to have it replaced, when it may just be the fluid level needing to be topped off. It is important to look at every aspect of each problem to get to the correct solution as quickly and efficiently as possible. The P code can be very serious as it can cause drivability issues. This is one of the codes that can leave a driver stranded on the side of the road. A good running engine means nothing without a properly operating transmission to transfer the engine power to the wheels.
It is a good idea to have this issue diagnosed and repaired as soon as possible. In order to help prevent trouble codes such as the P code, it is a good idea to replace the transmission fluid in your vehicle along with the filter if applicable at the recommended intervals.
Doing this will ensure that the internal parts of the transmission stay well lubricated and also prevents debris from causing a restriction within the transmission.

When the torque converter clutch solenoid valve is activated, the torque converter lockup clutch will engage creating a 1 to 1 RPM ratio between the transmission input shaft and the rotational speed of the torque converter.
If there is a big jump in engine speed, there is no lock-up. Get Access to Factory Service Manuals. Need more help?

Do you have the same problem? This DTC may also set if vehicle is driven over mountainous terrain. Possible causes are open fused ignition switch output circuit, faulty or stuck TCC solenoid, faulty torque converter, dirty transaxle fluid, low transaxle fluid level or non-standard vehicle configuration. Turn ignition on.
Using scan tool, read DTCs. Turn ignition off. Ensure pressure gauge hose is long enough so gauge can be monitored during test drive. Test drive vehicle in Drive at 50 MPH while monitoring scan tool and pressure gauge. Pressure gauge should indicate about 15 psi 1. As scan tool indicates lock-up, pressure gauge reading should jump. If operation is as specified, go to next step. If operation is not as specified, torque converter or TCC solenoid is faulty. Repair as necessary.
Check transaxle fluid for improper level or for presence of any debris. If transaxle fluid level and condition are okay, go to next step. Disconnect TCC solenoid harness connector. Using scan tool, measure voltage on fused ignition switch output circuit at TCC solenoid harness connector.Tvi online free
If voltage is greater than 10 volts, go to next step. If voltage is 10 volts or less, repair high resistance or open circuit. Measure resistance of TCC solenoid. If resistance is ohms, go to next step. If resistance is not as specified, replace TCC solenoid.
Test drive vehicle and maintain 50 MPH as indicated on scan tool. Achieve lock-up and wait 10 seconds. Record engine RPM. If engine speed was RPM, go to next step.

TCC connector:. I have a code p on my van. Do you. Was this answer. Please login or register to post a reply. P, P And C speed Sensor. I Know WhatIt is a generic trouble code to all makes and models of vehicles made since Specific steps for diagnosis and repairs may vary from on different models. It is located between the engine and the transmission and works by improving the torque output of the engine and drives the rear wheels. The engine and the transmission of the vehicle are connected together through a fluid coupling mechanism found inside the torque converter.
To determine which is which, make sure you consult factory wiring diagrams. There are lots of different diagnostic trouble codes associated with transmission control module. If there are additional transmission related trouble codes aside from the P, then the problem might be electrical failure.
Check the wiring harness of the transmission, look for any signs of damage and loose connections. Refer to your factory wiring diagram to locate the right power source and identify all the connection points between circuits.Abang sakit tolong berhenti wattpad
The transmission is triggered by the TCM through a power supplied by a fuse or relay. Disconnect the harness of the transmission in its connector, TCM and power source. Set the DVOM digital volt ohm-meter to ohm scale, and check the circuit for resistance using the positive and negative leads on their appropriate pins.
If resistance is too high or over the limit OLthen there must be a fault in the TCC solenoid or internal harness — some models may require the transmission oil pan to be removed for better diagnosis of the TCC solenoid. Then, using the DVOM again, set at ohm scaletest the wiring between the wiring harness connector and the TCM at the transmission case. The resistance should be very high or OL. Remove the harness plug of the transmission if applicable and then check the resistance of the TCC solenoid, as well as the internal transmission wiring at the transmission case.
Note that, some makes and models of transmission wire harness with TCC solenoid and internal harness as a single unit. If it is too high or OL, then remove the transmission oil pan and check the solenoid inside the transmission if applicable. Connect the positive lead at the wire to be tested, and the negative lead to a known good ground, with the vehicle key on and engine off. Battery voltage must be present. Since TCM is activated only during certain driving conditions, it is important to monitor the TCM using advanced scan tool to its performance, and whether it is commanding the TCC and what is in its feedback reading.
TCC is usually controlled by a duty cycle to engage more comfortable clutch management of comfortable torque converter. To test whether the TCM is sending signal or not, you need a graphing multi-meter set to conduct duty cycle or a digital storage oscilloscope. The positive lead is connected to the wiring harness that is plugged in the TCM, while the negative lead is connected to a known good ground.Theoretically you can drive for a few weeks or even months with a broken MAF sensor.
You will notice a decrease in gas mileage and over time the car will eventually start stalling a lot. So you should chech it on our car models. Disconnected, dirty or fouled spark plugs are common causes for engines that won't start. Spark plugs typically need to be replaced every season or 25 hours of use. You should also check that the spark plug gap is set properly. If your spark plugs look good, problems with your ignition system can also preventing a spark.
These can range from a faulty spark plug lead, shorted kill switch or flywheel key damage. Parts or components should not be replaced with reference to only a P DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing. Code Search Please fill the "Code Box" to find engine fault code.
