SOURCE: 2001 honda odyssey radio won't play, wants a code

The code number is different for all Hondas. There should be a credit card sized piece of plastic with the owner's manual with the number on it. If not, have your Honda dealer contact HONDA with the vehicle identification number (vin) to get the code. Write it down and keep it safe. You'll need it each time the battery is disconnected or you lose power for some reason. It's the anti-theft component of the sound system. Some dealers record the number where you can find it, such as inside the glove box, or inside the trunk overhead. It's a 5 digit number. Good luck!

DTC P0740: Problem in Lock-up Control System

As per Honda Service Bulletin 02-062 (January 5, 2007), DTC P0740 testing procedures have been replaced by the following:

Got an A/T DTC 0740? Don't Replace the Solenoids
If you're troubleshooting a '99-04 Odyssey for an A/T DTC P0740 (lock-up control system), don't replace the TCC, shift, or linear A/B solenoids if the A/T has more than 10,000 miles racked up. What's most likely causing this DTC is low line pressure resulting from the inlet screen being clogged with clutch material. To fix this problem, see additional information below, and replace the A/T.

I have a 20001 Odyssey with 70,000. The check engine light and TCS light both came on. The TCS light has since gone out but the check engine remains. I went to an auto parts store and their computer came...


unfortunately it is. Contact your local dealership to see if it may still be covered under a warranty or not.

Customer Concern: The check engine light is on with the trouble code P0740 present. Tests/Procedures: 1. Test drive the vehicle and watch the tachometer. See if the automatic transmission locks up. If unable to see the RPM change, and the Engine Control Module (ECM) is turning on the lockup solenoids, then the problem has to be internal to the transmission. The transmission has an extended warranty from Honda for 7 years or 100,000 miles. Potential Causes: Automatic Transmission
Lock-Up Solenoid
Torque Converter
Tech Tips: TSB #02-062 Diagnostic Codes: P0740

P0740 code on 2000 Honda Odyssey


Code p0740 is a problem in lock up control solenoid assembly, Check whether scan tool indicates another code. Does the scan tool indicate another code? YES - Perform the Troubleshooting Flowchart for the indicated Code(s). Do not continue with this troubleshooting until the causes of any other DTCs have been corrected. Measure the line pressure. Is the line pressure within the service limit? Repair the hydraulic system as necessary. Replace the Lock-up Control Solenoid Assembly set lock-up control solenoid valve/shift control solenoid valve A assembly and the A/T clutch pressure control solenoid valve A/B assembly. Turn the ignition switch OFF, and reset the PCM memory by removing the BACK UP fuse in the passenger's under-dash fuse/relay box for more than 10 seconds . Using the scan tool, check to be sure that the engine coolant temperature is 176°F (80°C) or above . Drive the vehicle at 55 mph (88 km/h) for more than one minute . Recheck for code P0740. Does the OBD II scan tool indicate code P0740? YES - Remove the torque converter and inspect for a missing torque converter O-ring. If the O-ring is damaged or missing, replace the transmission and torque converter. NO - The system is OK at this time.

Honda torque converter clutch solenoid circuit


P0740 is a Torque Converter Clutch Circuit Malfunction, you will need to have just this circuit tested, it is mostly just a defective Torque converter clutch solenoid in the trans or a defective connection to the trans, u do not need another overhaul.
