My sense is that these components last somewhat longer than first anticipated, probably because of the leaner mixtures we're using, and the no-lead gas. It can be expensive. But you probably could change out the oxygen sensor yourself. It's usually accessible, and it ain't brain surgery. The converter is another matter. Good Luck i had a metro with 250000 with original convertor and 02 the convertor is built into a section of pipe you get the whole thing for 150$ and replace it with four bolts and believe it or not the bolts usually are removable without having to use a torch
One O2 sensor is on the manifold after the first catalytic converter and the other O2 is downstream behind the second catalytic converter (middle of vehicle body underneath).
I have a 99 Metro 1.3L. This car has two oxygen sensors, one in the exhaust manifold and the other is after the Catalytic Converter. Hope that helps.
It has 1 O2 sensor located on the exhaust manifold befor the catalytic converter
They are blue, black and white. They can be found extending from the catalytic converter (the upstream O2 sensor) and possibly from a second source (the downstream sensor).
One. The stock Geo Metro from 1995 and on consists of a catalytic converter a resonator and the muffler. In sure it holds true for the earlier models as well
try cleaning or replacing the cylanders
I have a 1998 Metro with the 1.3l and the Camshaft Position Sensor is located on the bottom of the oil pan.
In front of and behind the catalytic converter.
It is inside of the transmission.
the seal on the crank shaft needs replaced
that must be some metro to have a big block
This code is generic and is the same on all vehicles. P0420 = Catalyst System Efficiency Below ThresholdCatalyst System Efficiency Below Threshold. This means that the secondary O2 sensor detects that the catalytic converter isn't working as efficiently as it should. This engine code can be triggered by any one of the following: 1.) The catalyst in the catalytic converter is cracked, clogged, or otherwise damaged. 2.) The secondary O2 sensor is malfunctioning. 3.) There is an exhaust leak. 4.) The computer unit is faulty
