ses -p1153 insufficent switching

[buckeyboy]

Hi again Guy;s my light came on again the other day and I scanned the code came up p1153 and p1133. ereased the codes next two time came up p1153 is the sensor bad or is somthing causeing this code?? If it is bad where is the sensor located 1997 4.3 any help would be appriciated.

I don't think I can be much help, because I don't have much experience with this code. That said, the code is referencing the O2 sensor in the passenger side manifold.

How were you clearing the codes, with a scanner or by disconnecting the battery? Just erasing them with a scanner doesn't reset the computer, you might try disconnecting the battery to reset then take it through a driving cycle to see if it comes back.

Some info I just found...

A complete driving cycle will perform diagnostics on all monitored systems and can usually be completed in less than fifteen minutes.


Cold Start. In order to be classified as a cold start the engine coolant temperature must be below 122°F (50°C) and within 11°F (6°C) of the ambient air temperature at startup. Do not leave the key on prior to the cold start or the heated oxygen sensor diagnostic may not run.

Idle. The engine must be run for two and a half minutes with the air conditioner on and rear defroster on. The more electrical load you can apply the better. This will test the O2 heater, Passive Air, Purge "No Flow", Misfire and if closed loop is achieved, Fuel Trim.

Accelerate. Turn off the air conditioner and all the other loads and apply half throttle until 55mph (88km/hr) is reached. During this time the Misfire, Fuel Trim, and Purge Flow diagnostics will be performed.

Hold Steady Speed. Hold a steady speed of 55mph (88km/hr) for 3 minutes. During this time the O2 response, air Intrusive, EGR, Purge, Misfire, and Fuel Trim diagnostics will be performed.

Decelerate. Let off the accelerator pedal. Do not shift, touch the brake or clutch. It is important to let the vehicle coast along gradually slowing down to 20 mph (32km/hr). During this time the EGR, Purge and Fuel Trim diagnostics will be performed.

Accelerate. Accelerate at 3/4 throttle until 55-60mph (88-96 km/hr). This will perform the same diagnostics as in step 3.

Hold Steady Speed. Hold a steady speed of 55mph (88km/hr) for five minutes. During this time, in addition to the diagnostics performed in step 4, the catalyst monitor diagnostics will be performed. If the catalyst is marginal or the battery has been disconnected, it may take 5 complete driving cycles to determine the state of the catalyst.

Decelerate. This will perform the same diagnostics as in step 5. Again, don't press the clutch or brakes or shift gears.

Great info. I am Just erasing them with the scanner I will try disconnecting the battery. That other info ya gave is pretty cool to know thanks.

I would say 1997 ignition switch failure or your MAF sensor needs replacing.

Ignition switch has been changed about 8 months ago when I was getting transmission codes. Maf? possible will have to see. thanks

If you are all of a sudden having O2 sensor failures like that, your MAF needs cleaning or more than likely replacing.

Thanks Blazer LT will try cleaning it.
