P0031 and P0051 02 heater control, P0131, P0151 and P0132 02 voltage P0748 pressure control solenoid a electric. Your 02 sensors not problem, problem is electric in nature
both are o2 sensor problems and should be related to each other p0151 -o2 senson malfunction bank 2 sensor 1[ which would be the sensor on the no.2 cylinder side ---before the cat conveter --the p1153 o2 bank 2 sensor1 insuffent switching --its the same o2 sensor -check the wiring and connection if good- than replacement of the o2 sensor is dvised
Reset error codes by disconnecting battery for 5 minutes. Start fresh. all codes should be clear now. drive and see if any new codes come on. They are the ones you need to address.
We guess DTC P0151... essentially the same as P0136 and P0137 and P0131, a P0151 code refers to the first oxygen sensor on Bank 2 . P0151 means the O2 oxygen sensor's voltage remained low for longer than 2 minutes. This, is interpreted by the ECM as a low voltage condition and sets the MIL. Bank 2 Sensor 1 is located in front of the catalytic converter.
There may be no visible symptoms to the driver, other than the MIL (Check Engine / Service Engine Soon) illumination.
A code P0151 may mean that one or more of the following has happened: Faulty o2 oxygen sensor Short to voltage on O2 signal circuit High resistance or open on O2 signal circuit
Possible Solutions: Replace faulty sensor Repair short, open, or high resistance on o2 signal circuit
02 sensor codes You have a vacuum leak some where, to include the intake manifold gasket. All three of these sensors would not go out at the same time.
Bank two oxygen sensor, located in front of the catalytic converter on the passenger side has failed. The actual code reads: P0151 - Heated Oxygen Sensor (HO2S) Circuit Low Voltage Bank 2 Sensor 1.
p1133 O2 sensor insufficent switching (pre converter, left bank)
p1153 ) 02 sensor insufficient switching preconverter right bank
P0420) catalyst system efficiency below threshold left bank
P0151) 02 sensor circuit high voltage pre converter right bank
and p1460 unfortunately I don't have handy..... But REALLY sounds like you need to replace the Oxygen sensors in front of the catalitic converters... There is dual exhaust coming from the engine to one muffler in that truck, there are a total of 2 converters and 4 O2 sensors (1 in front of converter and 1 behind it on both of the pipes) Front ones are definetely shot!!!! Be prepared to put the rear ones in shortly after!!!!! they are about $80 canadian each at the jobbers and probably more at the dealer!!!!!
