1153: Insufficient Switching Bank 2 Sensor 1

no clue what that means ... time for new plugs or a coil that is bad?


look up codes here: http://www.troublecodes.net/isuzu/iszuobd2.shtml


300 is a missfire code that could be plugs (or more commonly a bad intake manifold gasket (I had mine replaced 2x within 75k).

if your plugs have more than 65k on them swap them out.

see the link below for some Isuzu maintainance FAQs

Thank you Amigo-2K
Do you know where bank 2 sensor 1 is located on a 98 Rodeo V6 5 speed? Driver or passenger side? before or after the Cat?

Bank 2 is the side of the engine that does not have #1 cylinder. So, it should be drivers side. Sensor 1 is before the cat.

The p0300 is probably responsible for toasting your O2 sensor. You need to figure this one out before your cats melt down.

P0155 refers to a malfunction of the O2 heater circuit on the same O2 sensor mentioned in the p1153.

You could try changing the O2 sensor and that might fix something and then replace the plugs might fix the p0300.

Yesterday, I changed O2 (Bank 2 sensor 1), cleared codes and no error codes so far.
Thank you guys and I wil keep posting if somthing happens.

The 1153 means the O2 sensor isn't switching voltage up/down as fast as the ECM thinks it should to maintain optimum air/fuel ratio on that bank. The ECM expects it to be constantly changing voltages based on the oxygen level in the exhaust. Old or contaminated sensors tend to slow down, but vacuum leaks or a leaking injector etc. can also cause it. It's not unheard of to get a new sensor that isn't up to par. I suggest you switch your new sensor with another one (all four on your car are the same) and see if the trouble code follows the sensor. If the same code comes back after erasing it, it's safe to conclude your new sensor is good.

The 02 sensors are very sensitive and an intake gasket leak on one bank could trigger the code on that bank and not the other. An OBDII scan might help isolate the cause. A scan can show the real-time activity of all O2 sensors, fuel trims, manifold vacuum, etc. I don't know if places like AutoZone will do a free scan or if they only read codes. Might be worth asking. Although if they do a scan, they may not be able to interpret the results (correctly). Other than that, I suggest you do the standard checks for air leaks on manifold gaskets, vacuum hoses, etc. and do a plug reading to see if one cylinder or bank is running leaner or richer than the others.

The P0303 code identifies a misfire coming from the # 3 cylinder (middle cylinder on the passenger side). Could be a bad plug, coil, injector, wire, or simply a bad wire connection on the coil or injector. I'd check/clean the wires and connections at the coil & injector, and pull the plug and check it. If everything looks good, you might want to swap the plug and coil with another cylinder and see if the misfire code changes to the other cylinder. The misfire code is P0300 for random misfire, P0301 for cylinder #1, P0302 for cylinder #2, P0303 for cylinder #3, etc., etc.

My mantra is to check and rule out the easy & cheap stuff first before spending $$. Good Luck & let us know what you find.
