2004 Accord speedometer problem
Hi. I got a 2004 Accord with 2.0l manual. It's been awesome car so far, but there's a problem with one thing: the speedometer.
When I'm driving it, in the city or highway, the speedometer needle suddenly starts wiggling between the speed I'm driving and 0. After a while it stops to 0, and after another while it starts working normally. After that, usually the obd gives me code P0720, if i remember correctly. Also, when it goes to the 0 or wiggles there, i feel like the engine bugs too, loses some power. I started studying and I'm kind of saving so i figured I'd ask here firs before buying anything. So, where should i start? |

Re: 2004 Accord speedometer problem
P0720 is an issue with the output shaft speed sensor circuit.
On U.S. models, this is a description of the speedometer: Speedometer The speedometer is controlled by the power supply circuit/controller area network controller built-into the gauge control module. The power supply circuit/controller area network controller receives vehicle speed information from the ECM/PCM through the fast controller area network transceiver via the MICU system. The ECM/PCM receives vehicle speed information from sensors within the manual or automatic transmission. The output shaft speed sensor is commonly used for the speedometer. Part no. 9 is the output shaft speed sensor in the following parts diagram. First take a look and check the connector and wiring. https://cimg8.ibsrv.net/gimg/honda-t...15f6123e80.jpg |
