These sensors have a separate circuit that heats them along with the oxygen sensor signal circuits. As the engine coolant temperature decreases below a particular temperature, the PCM turns on the oxygen sensor heater.<\/p>\n<p>The PCM continues to put on voltage to the heating element until it reaches a closed-loop operation. Once the engine attains a standard operating temperature, the PCM will stop providing voltage to the heater circuit. The PCM logs the code when it detects resistance from the heater circuit that\u2019s not in the required range.<\/p>\n<h2>What are the symptoms of the P0053 code?<\/h2>\n<p>These are the signs that you can observe when the code triggers in your car.<\/p>\n<ul>\n<li>The check engine light illuminates<\/li>\n<li>Decreased fuel economy<\/li>\n<li>The engine has a hard start<\/li>\n<li>Black or white smoke coming from the tailpipe<\/li>\n<li>Your car has a delayed start because of a cold, lean start condition<\/li>\n<li>The engine stalls<\/li>\n<li>Presence of other error codes<\/li>\n<\/ul>\n<h2>What is the cause of P0053?<\/h2>\n<p>These are some reasons why the code shows up in your car.<\/p>\n<ul>\n<li>A defective HO2 sensor<\/li>\n<li>The engine has a vacuum leak<\/li>\n<li>Severe exhaust leaks<\/li>\n<li>The oxygen sensor circuit has defective or short wiring<\/li>\n<li>Defective or disconnected electrical connector<\/li>\n<li>Severe or low fuel pressure<\/li>\n<li>The HO2S sensor has a blown fuse<\/li>\n<li>A faulty PCM<\/li>\n<li>Damaged engine control relay<\/li>\n<\/ul>\n<h2>How to fix the P0053 code<\/h2>\n<p>First, you must verify the error code using a scanner. Then, follow the steps to fix the engine code P0053.<\/p>\n<ul>\n<li>Reset the engine code and do a test drive again to check whether the check engine light illuminates again, and then use the OBD-II scanner to check whether the code reappears after the engine is set at operating temperature. If the code reappears, inspect the resistance of H2OS wiring to make sure it is around 8 ohms.<\/li>\n<li>Then, check the connector and wiring to the sensor to make sure the wires aren\u2019t damaged, broken, or melted to the exhaust system. Fix the connectors and wiring with the right parts and wiring type to ensure proper working.<\/li>\n<li>The heating oxygen wiring and sensor are very much prone to damage as they\u2019re close to the body. It is best that the wiring be held away from the exhaust.<\/li>\n<\/ul>\n<h2>How much does it cost to fix the P0053 code?<\/h2>\n<p>Depending on the issue, the cost to fix the P0053 engine code costs from $150 and can go above $600.<\/p>\n<p><strong>Common fix costs<\/strong><\/p>\n<table>\n<tbody>\n<tr>\n<td width=\"301\"><strong>Type of repair<\/strong><\/td>\n<td width=\"301\"><strong>Estimated cost<\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"301\">O2 sensor<\/td>\n<td width=\"301\">$100-$400<\/td>\n<\/tr>\n<tr>\n<td width=\"301\">PCM replacement<\/td>\n<td width=\"301\">$800-$1,200+<\/td>\n<\/tr>\n<tr>\n<td width=\"301\">Wiring<\/td>\n<td width=\"301\">$50-$120<\/td>\n<\/tr>\n<tr>\n<td width=\"301\">Blown fuse<\/td>\n<td width=\"301\">$20-$100<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<h2>Can I drive with a P0053 code?<\/h2>\n<p>Though you can drive short distances with this error code, we don\u2019t recommend it.
