How to test the solenoid on a Honda Accord?
TEST 1: Shift Solenoid A Resistance Test. Manually applying 12 Volts to shift solenoid A . In this test, you’ll use a jumper wire to apply power (from your Honda’s battery) to shift solenoid A and listen for a clicking sound. Resistance testing the TCC lock-up solenoid. .
What does a torque converter clutch do on a Honda Accord?
It means that the Accord ‘s computer has detected that there is an issue with the torque converter clutch (TCC) solenoid circuit. The TCC “locks” the drivetrain, which allows for a true mechanical connection between the transmission and the engine.
How does the transmission work on a Honda Accord?
The Accord uses a clutch in the torque converter to lock the engine and transmission together at highway speed. P0741 can register whenever this connection is not happening at all or happening properly.
What does the solenoid valve on a torque converter do?
The torque converter clutch solenoid valve switches the hydraulic circuit to engage/disengage the torque converter clutch. When the torque converter clutch solenoid valve is turned ON, hydraulic pressure is applied to the torque converter clutch.
TEST 1: Shift Solenoid A Resistance Test. Manually applying 12 Volts to shift solenoid A . In this test, you’ll use a jumper wire to apply power (from your Honda’s battery) to shift solenoid A and listen for a clicking sound. Resistance testing the TCC lock-up solenoid. .
How to test the resistance of a TCC solenoid?
Resistance testing the TCC lock-up solenoid. . This test simply involves measuring the resistance of the TCC lock-up solenoid and comparing the value with the factory spec of 12-25 Ohms. TEST 1: TCC Lock-up Solenoid Resistance Test. Manually applying 12 Volts to the TCC lock-up solenoid. .
Where are the solenoids located on a Honda?
Your Honda does not move with shift lever in manual 2 position, but does in D4, D3, R and manual position 1. The solenoid assembly is made up of two solenoids. One is the torque converter clutch solenoid and the other is the shift solenoid A. The solenoid assembly is located on the exterior of the transmission housing and bolted down by 3 bolts.
How is the torque converter clutch solenoid controlled?
The fluid pressure that applies and releases the torque converter lockup clutch is controlled by the torque converter clutch solenoid. The opening and closing of the TCC solenoid valve is controlled by the transmission control module (TCM) or powertrain control module (PCM), depending on the vehicle.
When to use the p0730 gear ratio code?
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 P0730 code will appear once this ratio is calculated from the sensor data in the transmission.
What happens when you put the p0730 code on your car?
Eventually, the P0730 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.
How to fix Honda shift control code p0730?
How do I fix code P0730 HONDA Check the “Possible Causes” listed above. Visually inspect the related wiring harness and connectors. Check for damaged components and look for broken, bent, pushed out, or corroded connector’s pins. P0730 HONDA Tech Notes Start by inspecting the transmission fluid level and condition, and change fluid if necessary.
Eventually, the P0730 code will cause the Check Engine Light to illuminate on the dashboard.

What is the OBD code for incorrect gear ratio?
P0730 is the OBD-II generic code for an incorrect gear ratio detected in an automatic transmission.
Your Honda does not move with shift lever in manual 2 position, but does in D4, D3, R and manual position 1. The solenoid assembly is made up of two solenoids. One is the torque converter clutch solenoid and the other is the shift solenoid A. The solenoid assembly is located on the exterior of the transmission housing and bolted down by 3 bolts.
