9141 does not exist I will assume it is DTC P0141 HO2S Heater Performance Bank 1 Sensor 2
The VCM has the capability to monitor this process by using the Heated Oxygen Sensor (HO2S Bank 1, Sensor 2). The HO2S (Bank 1, Sensor 2), located in the exhaust stream before the catalytic converter, produces an output signal which indicates the storage capacity of the catalyst; this in turn indicates the catalysts ability to convert the exhaust emissions effectively. If the catalyst is functioning properly, the HO2S signal will be far less active than the signal produced by the Heated Oxygen Sensor (Bank 1, Sensor 1).
When the HO2S temperature measures below 360°C (600°F), the sensor will not produce any voltage and will behave like an open circuit. This will result in an Open Loop operation.
The HO2S heater provides for a faster sensor warm-up which allows the sensor to become active in a shorter period of time and remain active during long extended idle. The DTC P0141 determines if the HO2S is functioning properly by checking the response time of the sensor. This DTC is a type B DTC.

Left side of the dash, to the right of the IP fuse block. Its a 25 amp circuit breaker, an aluminum cased breaker. CHECK FOR POWER ON THE SEAT SWITCH "A" TERMINAL AND GROUND ON THE "D" TERMINAL. IF YOU HAVE POWER AND GROUND THE SWITCH IS BAD.
