Hello,
I have a 2005 BF225 on a 24 Proline that has been giving me some issues.
Initially I had a bad VTEC sensor (fault code 21). After replacing that I put 10 hours on the motor before I got another alarm, this time fault code 21. I swapped out the oxygen sensor with a different (used) one and fired the engine back up, but immediately got an alarm (this time fault code 41). Thinking both sensors were bad I bought a new O2 sensor, to no avail.
I've checked the voltage of the heater wires at the sensor connector and get a steady 14.4 volts. I've disconnected and cleaned all connections at the ECM (though they weren't corroded) and nothing; the alarm comes on 6 seconds after starting the motor. Any ideas what the problem could be? Would a bad ECM or short in the wire still give a solid reading at the connector?
Any help or ideas are greatly appreciated.
