What does engine code 9141 mean for a 95 gmc jimmy
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.
