SOURCE: p134, p0141, po300, po130 and po135. 2005 Sunfire.

Given that most of the trouble codes are for the O2 sensor, I think I would change it. The multiple misfires could be because of improper fuel/air mixture caused by a bad sensor. Disconnect the negative(-) battery terminal then change the sensor. Disconnecting the negative(-) should reset the computer and allow the fuel/air mixture to return to default allowing the engine to start.
P0130 - O2 Sensor Circuit Malfunction (Bank 1 Sensor 1)
P0134 - O2 Sensor Circuit No Activity Detected (Bank 1 Sensor 1)
P0135 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 1)
P0141 - O2 Sensor Heater Circuit Malfunction (Bank 1 Sensor 2)
P0300 - Random/Multiple Cylinder Misfire Detected

SOURCE: 98 jeep grandcherokee code PO138,

P0138 - O2 Sensor Circuit High Voltage Bank 1 Sensor 2

The rear heated oxygen sensor (or sensor 2), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. Even if switching characteristics of the heated oxygen sensor 1 are shifted, the air-fuel ratio is controlled to stoichiometric, by the signal from the heated oxygen sensor 2. This sensor is made of ceramic zirconia. The zirconia generates voltage from approximately 1V in richer conditions to 0V in leaner conditions. Under normal conditions the heated oxygen sensor 2 is not used for engine control operation.

Causes:
- Harness or connectors (The sensor circuit is open or shorted)
- Rear heated oxygen sensor (Bank 1) may be faulty

Solutions:
Replacing the O2 Sensor 2 usually takes care of the problem


P0141 - O2 Sensor Heater Circuit Malfunction Bank 1 Sensor 2

Causes:
- Harness or connectors (The sensor circuit is open or shorted)
- Rear heated oxygen sensor (Bank 1) may be faulty

Solutions:
Replacing the O2 Sensor 2 usually takes care of the problem


P0463 - Fuel Level Sensor Circuit High Input

The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the ECM or PCM, It consists of two parts, one is mechanical float and the other side is variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.

Causes:
- Fuel level sensor circuit harness or connectors is open or shorted
- Fuel level sensor may be faulty

Solutions:
Replaced fuel level sensor.

SOURCE: replaced:plugs,wiresdistributor,fuel pump.truck wouldn't start before

P0135 means 0xygen heater circuit malfunction, P0141 mean 02 heater circuit bank1 sensor 2 (this is catalytic monitor) P0147 means 02 heater sensor circuit bank 1 sensor 3, P0300 is random misfire. You will get all the 02 code because of the misfire correct the misfire and the 02 should correct.We will start with the plug wire and make sure the firing order is correct 1996 chevy blazer that will make it a 4.3 engine size check the firing order firing order is 165432 also check the coil (it has a tendency to short you will know if it is) cansmo_181.gifcansmo_182.gifmake sure the distributor rotation is check

2005 jeep grand cherokee Po204 205 175 174 138 158. Runs rough. Whats wrong?


PO204,205 are injector circuit malfunction,PO174 is a system lean code, PO175 is system rich code, PO138 is heated oxygen sensor bank1 sensor 2 circuit high voltage, PO158 is heated oxygen sensor bank2 sensor 2 circuit high voltage. This is a repair for your mechanic. When they fix the injector and o2 circuits the rich lean codes will also be repaired. Continued driving will ruin your catalytic converter. Good luck

2006 Dodge Caravan Getting Two codes: Po135 and Po141


Sadly people don't know that trouble codes only tell the mechanic what to test, not what to replace. And auto parts stores are in the business of selling parts, not giving advice.
Code 135 means there is a problem with the heater inside the o2 sensor for bank one in front of the catalytic converter. Code 141 means the same thing for the o2 sensor after the cat.
Since it is very rare to have two O2 sensors fail at the same time, chances are the problem is lack of power going to the sensors.
The power circuits would need to be checked which requires a shop manual to get the testing procedures and wiring diagrams.

I have a 2005 Hyundai Elantra, now shows a PO138. Where is it? I think there are 2, need this location


code p0138 refers to ho2s and o2s both in bank 1 both causes ---wiring---short to positive- Replacing both sensors in bank 1 should fix the fault ---ensure that you use the correct tool for this as anything else will twist the wires and cause faults.

Po135 code on 2001 jeep have replaced up stream frt. sensor


Dit you check the fuse? Jeeps many times ha e problems with Bosch sensors due to the slower heating. Best is to use Denso.

Can ODB2 READERS READ THE TRANSMISSION TEMP ON THE


code readers cant.the scan tools can but are real expensive.if you havent drained the trans oil yet just drive it around a while and check it.if you have drained the oil then try to measure what you took out and put that much in.if you cant measure old oil then add fluid while engine running in nuetral{double check the nuetral position writen on dip stick} add fluid untill oil is below the add level let it run for a while say 30 minutes and recheck add th full then go drive it around.recheck again if low add if high drain out or siphion some out throuh small hose through the dip stick tube
