Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector's pins. How much do you know about cars? Take the AutoCodes. The auto repair labor rates vary by location, your vehicle's make and model, and even your engine type. When is the code detected? The TCM detects tcc slippage greater than calibrated value. Lock-up piston operation will then be controlled.

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.

A P can be triggered while shifting between gears or when driving at a steady speed in any gear the transmission is designed to utilize. P is usually triggered when there is a problem during shifting gears. Being it a generic trouble code, P does not necessarily pinpoint any specific gear ratio failure.

In other words, the trouble code does not indicate which one of your vehicle's gear s is failing. Instead, it simply advises that there is a problem between the transmission's expected output and input RPMs. These should be fixed first before fixing the incorrect gear ratio problem. More than likely the issue causing the P will be resolved during the correction of the prior codes. Here are some common faults which may cause a P to be stored with the engine computer system:.

What caused my vehicle to set a P trouble code? Bad fuel economy. Unable to drive at high speed. How can I fix a P problem and where should I start? We first recommend pulling the trouble code s from the ECC, along with the freeze frame data.

The freeze frame data will give you information on the engine's exact operating condition at the precise moment the trouble code was triggered. Write down or record this information somewhere. Next, clear the ECC and drive your vehicle for at least miles or until the check engine light turns on again. Try and re-create the engine condition using the freeze frame data.

If the check engine light returns, extract the trouble codes and verify that trouble code P is still present.

If so, move on to inspecting the transmission fuse s. Ensure none are defective. Next move on to checking the wiring harness and wiring connections to the transmission for damaged. If the wiring to the transmission control module and torque converter clutch solenoid are not damaged, your next step would be to test the TCC solenoid itself, as well as verify the TCM is commanding the solenoid on power at solenoid when activated by TCM.

This diagnosis is a bit more complicated and may require an experienced technician.

I have dried the Floor Board out as much as I could. After replacing the Heater Core, the truck drove fine. I did see the radio going in and out and the horn would blare out of nowhere. So I assumed something got wet. But not sure what exactly. Truck still drove fine. I put about 60 or 70 miles on it since the Heater Core was replaced. NEVER a shifting or transmission issue. Only started after the Power Steering Pump was changed. Which leads me to believe he did something Here are the codes I checked all fuses and swapped relays for the EATX.

No Change!!!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 is on diagnostic inspection. The P code identifies a problem within an automatic transmission. The ratio of a combination of engine speed and throttle position and the speed of the transmission is used to determine what gear the transmission will use when driving.

If there is a problem with any gear within the transmission, then the P code will appear once this ratio is calculated from the sensor data in the transmission. Eventually, the P code will cause the Check Engine Light to illuminate on the dashboard. Along with this indicator, there may also be slipping within the transmission and poor overall transmission performance.

The transmission may stay in a low gear for too long, or stay in a high gear until the engine stalls. Fuel economy may worsen as well. Prior to further diagnostic tests, the fluid in the transmission should be checked for quality, and the level of fluid should be noted.

Old or dirty fluid should be replaced. This will provide them with the necessary information from the engine that they can view in real-time. The code will be cleared and the mechanic will take the car for a test drive. If the code comes back, then the code was caused by an actual problem in the transmission. Depending on the severity of the issue, the technician may perform a torque converter stall speed test to determine if the engine stall speed is within factory specifications.

The engine speed must match the readings from the transmission sensor. The biggest problem that pops up when diagnosing the P trouble code is that the symptoms may all be stemming from low or dirty transmission fluid.

Topping off or replacing this fluid may solve all of the issues in the transmission triggering the trouble code. The severity of P code depends mostly on the application. In some cases, minor issues can trigger the code, due to the fact that any abnormality in the transmission speed will trigger it in any gear. It could also be triggered when there is a major problem with the transmission, rendering it unable to change gear, though it would likely be accompanied by other, more specific trouble codes.

When the P code appears it is best to have it diagnose by a qualified technician. In many cases, the problem goes away as soon as the code is reset once, especially in cases where the Check Engine light appeared immediately upon startup. If the Check Engine Light comes on because of the P trouble code right when the vehicle starts, then it can probably be fixed by simply resetting the code. Small problems with the wiring, common in aging vehicles, can easily trigger certain trouble codes without the presence of a serious problem.

When the P code appears, it often does so alongside several other error codes. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle.

When you fill your car with gas, the vapors in the tank get forced into a canister filled with activated charcoal. Also, on a hot day as the gas heats up and vaporizes, those same vapors push into the canister where they're stored.

But the charcoal can only hold so much vapor. At some point it has to be emptied. The emptying process is called canister purge. Gasoline engines use spark plugs to cause an explosion of fuel within the cylinder. In a properly timed engine, this explosion occurs at the proper moment to send the piston to the bottom of the cylinder and provide power to the drive shaft.

If the plug wires are out of sequence, the explosion occurs at the wrong time. The improper timing of the explosion sometimes pushes the cylinder the wrong direction or interferes with the turning of the crank. As a result, the engine stutters or backfires, if it runs at all.
