SOURCE: 95 gmc jimmy engine codes

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.

Disconnect the heater hoses from the water pump and the intake manifold. Get a compressor and blow out the hose (put the air hose into the the hose that came off the mainfold. then flush the system and replace the antifreeze.

SOURCE: need to replace passenger side view mirror 200 GMC Jimmy Diamond

On my '97, there was a triangular shaped piece of plastic on the inside trim that had to be removed. I think all three mounting screws were under that. It's been a few years, but I think that was how it was done.
I remember it was pretty easy though.

1998 gmc jimmy is knocking


There are several things that could cause a knock, ranging from a worn crankshaft bearing(s) to a worn water pump.

You can further pinpoint this knock by defining if it occurs occasionally, constantly, just at a specific RPM, or only under a load.

What kind of a knock is it? Hi-pitched or low-pitched?

A more detailed problem description would yield you a more specific/helpful answer.

1991 4.3L GMC Jimmy S-15 will not start. Turns over, but does not start. Replace spark plugs and wires, ignition coil, module checked good. The plugs are gettin fire but not sending it to the motor?


You need 3 things.
Compression
Good hot blue spark to all plugs.
Good gasoline and proper fuel pressure. 13-13.5 lbs on your TBI
If you have all 3 then move on to injector pulse to both injectors.

Keep me posted and recheck your spark plug wire to make sure they are not crossed. firing order 1-2-3-4-5-6 cylinder # passenger side 1-3-5 front to back. cylinder # drivers side 2-4-6 front to back
distributor #1 is located at the 7 o"clock and rotates clock wise so next distributor post on the right working clock wise is #2. Good luck and hope this helps.
