Chevrolet Metro Oxygen Sensor
The Oxygen Sensor found in Chevrolet Metro cars is important in determining the amount of the oxygen that remains unburned in the exhaust so as to regulate the air-fuel mixture mix proportion and hence reduce emissions. The voltage signal hence produced by the sensor is fed back to the engine control computer so as to allow it to manipulate the pulse width of the fuel injector to create efficient combustion. Chevrolet Metro car models mostly install zirconium dioxide types of oxygen sensors and these may be the Narrow and the Wide Bands. The narrow-band sensors produce voltage signal that swings between rich and lean conditions, whereas wide-band sensors provide greater measurement range for more accurate air fuel ratio management. Thus, these sensors are subject to contamination over a period of use, and then the emissions increase and fuel efficiency decreases. Chevrolet Metro vehicle requires constant checkups and maintenance of the Oxygen Sensor for it to perform efficiently at all times.
Each OEM Chevrolet Metro Oxygen Sensor we offer is competitively priced and comes with the assurance of the manufacturer's warranty for the part. Furthermore, we guarantee the speedy delivery of your orders right to your doorstep. Our hassle-free return policy is also in place for your peace of mind.
Chevrolet Metro Oxygen Sensor Parts Questions & Experts Answers
- Q: How to Check and Replac Coolant Temperature Sensor,Crankshaft Position Sensor,Intake Manifold Temperature Sensor,MAP Sensor,Oxygen Sensor,Throttle Position Sensor and Vehicle Speed Sensor on Chevrolet Metro?A: Most components in 1989 through 1991 Geo Metro models have an extended warranty coverage from the government which makes it difficult to perform component checks or replacements during the warranty period. Both sensors found in electrical position determine exhaust gas oxygen levels within the exhaust manifold and catalytic converter which detects emission levels respectively where circuit failures produce code 13. A failure within the TBI unit coolant temperature sensor thermistor will trigger a code 14 or 15 while a check requires resistance tests with an ohmmeter and replacement with Teflon tape or thread sealant to stop leaks. A failure in the manifold air temperature (MAT) sensor located in the air cleaner housing produces a code 24 which should be diagnosed by a dealer. A faulty manifold absolute pressure sensor cannot be repaired thus it requires complete unit replacement because it transforms the manifold pressure fluctuations into an electronic signal for fuel control through ECM. Manual transaxle cars use a throttle switch (TS) to check throttle valve angle whereas automatic transaxle vehicles utilize a throttle position sensor (TPS) to accomplish the same function. Both devices trigger error codes 21 or 22 that demand professional diagnostics for proper fix. A failure of the vehicle speed sensor (VSS) which is integrated with the speedometer causes a pulsing voltage signal to the ECM for speed calculation and produces error code 24. This diagnosis requires professional attention from a dealer. Engine speed calculation and device control operations derive from the crank angle sensor which exists as a component of the distributor to produce alternating voltage pulses.
