My 2006 Accord EX 2.4L thew P 2185 engine coolant temp sensor 2 circuit high and 61-1 ABS Battery Voltage malfunction. The guy at advance auto said he doesn't know what those codes mean and told me to go to the dealer.

 

Make sure battery is good and battery connections are clean/secure. Low battery voltage could cause ABS 61.

P2185 is an electrical fault in the Engine Coolant Sensor 2 electrical circuit; faulty sensor, connector, wiring fault, or PCM fault.

Suggest first disconnecting, cleaning electrical contacts (sensor and connector), and reconnecting sensor 2. Sensor is lower driver's side of radiator. Splash shield must be removed.

Next check sensor 2 resistance w/ connector removed. If open or short circuit, problem is the sensor.

If sensor checks OK (finite resistance of a few Kohms at cool temperature), then a wiring/connector fault must be investigated.

If wiring is good, the PCM is problem.

good luck
