Where is location of heat sensor - 1994 Oldsmobile Ninety Eight Regency

catalytic converter .
In order to control emissions, a catalytic converter converts any harmful exhaust emissions into harmless water vapor and carbon dioxide.
The powertrain control module (PCM) has the capability to monitor this process by using a rear-heated oxygen sensor (HO2S 2). The HO2S 2 , located in the exhaust stream past 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 2 signal will be far less active than the signal produced by the front oxygen sensor (O2S 1).

Bank 1 is located towards the driver's side. Sensor 1 is located upstream just below the exhaust manifold.
EOBD II Error Code: P0134
Description:
Oxygen Sensor (O2S) 1, Bank 1/Heated Oxygen Sensor (HO2S) 1, Bank 1 - No Activity Detected
Possible Causes:
- Wiring.
- Signal wire between the Heated Oxygen sensor and ECM is disconnected.
- Heated Oxygen Sensor defective.
- ECM.

do you mean "coolant sensor" and witch engine

The bank has to do with which side of the engine. The 'Sensor 1' indicates that it is upstream of the catalytic converter.

There is no fuel heat sensor on this vehicle? possibly something else your looking for?

Hi:
The Number 1 Heated Oxygen sensor is located in front of the catalytic converter. You would need to get the car up in the air, and then disconnect the electrical connector, and possibly need a special socket to remove the sensor. Also remember to purchase and use Oxygen sensor safe anti sieze compound on the threads of the new sensor, if you do this your self

I hope help you with this (rated this help). Good luck.
